Windows is always going to be proprietary software, so I’m never going to give it the time of day.
Next question.

Because it makes doing the things I want to do with a computer difficult and annoying.

I dual boot on my primary/desktop PC, and only run Linux on my laptop and Steam Deck.

I find more often times than not, I feel like I'm either fighting with Windows or it does these small but annoying things that when added up tend to really get on my nerves. For example, one thing that I've been running into a lot (and happened earlier today) is if I put my computer to sleep while its booted into Windows, it'll randomly decide to wake itself up for who knows what reason - flooding my room with light often times while I'm trying to sleep or relax. It does it enough where I should by now remember to just physically turn off my monitors when I put my computer to sleep, but why should I have to? The 95% of the time that I'm booted into Linux, if I put my computer to sleep it stays asleep until I explicitly wake it up, and thus I haven't formed a habit to turn the displays off.

The only reason why I even keep Windows around on this PC is to occasionally play Destiny 2 and some VR stuff with friends every now and then.

Honestly, privacy and freedom of choice alone is why I switched back.

I will give windows credit, it's definitely better than any other platform out there when it comes to support and it is really nice just having things "just work". I went relatively 8 years having almost zero issues with gaming with the exception of my graphics driver which was a fault of AMD not necessarily Microsoft. All I would have to do is install a program maybe restart the computer and then run the program the way I went. With my current system I can't even guarantee if the software I want to use will work because the ecosystem is geared towards Microsoft so every product out there is Microsoft first Unix if we get around to it.

My only reason for switching was the lack of choice I was getting. While I never had to restart for updates because it automatically updated nightly when I turned it off so it was very non-invasive, the fact that I I wasn't trusted enough with my computer to be able to turn those updates completely off if I wanted to, on top of the fact that every major update seemed to hard push the office suite, and every update seemed to respect my privacy less and less was already putting me on the edge of switching every time that I had it happened to me.

But the recent rumor wave that was going through that Windows 10 when it reached end of life wasn't going to be the same way that every other OS that they've had has been where they will release security updates past closing and instead they're going to open the business only support tier to your Standard customer and offer Windows 10 at a subscription price instead, on top of the fact that Windows 11 wasn't going to support how I wanted to set my computer up without having to reinstall it anyway, I just took the plunge and went back to Linux. Overall it has been enjoyable, but I really do miss the ease of being able to just install something and have it work that comes with being in the dominant ecosystem. That being said, It is nice not having to worry about what a mega company thinks I should run the computers that I paid for, built, and set up myself.

Poor workflow. Switching applications is horrible if you have 4 windows open in one desktop. Even gnome is far better at that.

I think hate is really too strong of a word, dislike at most for me.
My biggest issue with Microsoft is a lack of trust. Apart from that, I just like my Linux setup more and find it easier to use.
Stuff I want to do works how I want to do it and how I'm (now) used to it.
Regardless, I use Windows at work, manage Windows Servers and Azure. It's just how it is.

Hate is a strong word, indifferent is more the word I'd use.
And I'm indeifferent because I have used (GNU)Linux as my main desktop OS since 2005, and (GNU)Linux exclusively for the past 15 years. And now even games run fine on Linux, so to me it's all benefits now.
So it's just that Windows and everything Microsoft is irrelevant now, except for a classic game I still play occasionally with my wife.

Obviously the proprietary nature with all the problems that includes, was what motivated me to shift originally, and it is also the reason I don't even want to dual boot Windows, not if it was free as in beer either.

3. The joy of “figuring it out”

No absolutely not, I used to be an IT consultant, but like most people I like things to just work, and Linux has done that for many years now.
I do however like the freedom, and that I am not prevented from configuring my system like I want to. I remember Windows having the most ridiculous mechanisms to prevent me from for instance replacing something as banal as notepad as default/system text editor. Absolutely bullocks behavior by Microsoft IMO. I am very happy to have a system where I decide, and not some company that wants to lock me into their ecosystem.

PS: I have never tried anything Windows beyond Windows XP. But boy did Vista and Windows 8 convince me that I did the right thing switching to (GNU)Linux. Almost everybody I know were absolutely pissed about both.

Windows Vista was the most golden opportunity to buy expensive hardware for cheap, because it didn't have drivers for Vista. Laughing my ass off about people who claim hardware lacks drivers for Linux, when it's actually worse on Windows with every new release.

A few months ago I blindly copied the hosts file from https://github.com/Ultimate-Hosts-Blacklist/Ultimate.Hosts.Blacklist as I was used to on BSD and Linux systems. It bricked Windows. Turns out that I had to use the installer script for Windows. Realised too late. That was my final goodbye to the Redmond giant.

For running a walled garden with iron grip, Apple allows copying the hosts file. Which I use for things like certification exams and any governmental agency stuffs.

I find Linux to be MUCH easier to use. Granted, this is unusual, especially for an i3wm user, but hear me out: Although Linux has a very steep learning curve and using it seems very hard at first, this difficulty is short-lived. Getting anywhere is significantly faster and requires fewer steps, and the "simplicity" of windows quickly turns into complexity when you actually want to multitask and keep having to resize and click through dozens of windows.

Of course, I also really like the freedom of actually owning my system, and that of tinkering with all the software on it when I am annoyed at something not being how I'd like. Privacy is a nice bonus, but honestly the lesser concern since I already have none anyway by owning a phone and being too lazy to degoogle it.

I don't hate Windows but I hate being forced use it. I feel that I'm very effective when using Linux and just don't like when I am being slowed down. I want to use my machines to get things done and don't like it when operating systems and tools get in my way instead of enabling me to do what I need to do. Hating Windows is pointless because it's a waste of energy: it is what it is, why expect more?

Even with all the privacy concerns aside, I absolutely fucking despise it, when I cannot use my computer the way I want it to be used. That alone would have been enough to convince me to switch. Not to mention that trying to fix issues is a waste of effort, because the system internals are obscured into oblivion. Looking up any issue results in a generic "have you tried turning it off" answer from a Microsoft forum bot.

I like how the Linux kernel works, and I like how things around it are designed. It's much simpler, a lot more straight-forward, and I can setup shit how I like it. It's almost as if people who are working on Windows know that they want to tighten their grip over your system, to the extremes, but at the same time, don't have the reputation of Apple, to be let off the hook, when they pull complete bullshit moves every time

Most Linux distributions and thus development feel like passion projects. Each time I try to revisit Windoze I feel like the product. That’s completely ignoring the customization I am provided in Linux. I don’t care about ricing. I just want a functional machine tailored to my use case, which is easier to do on FOSS.

I haven't used Windows in years and rarely think about it. But, ads. I hate ads with the burning fury of a thousand suns. Therefore, MS catches some fraction of that hate by putting them in the OS.

Convention over configuration feels like such a fight when I'm trying to configure something

Maybe they are new users who miss Windows, so they are trying to find reasoning to stay on Linux. I as an old user have no more any special emotions about Windows. I play with it form time to time. But the OS is quite conservative because of its market monopoly and I don't find anything new and interesting in new releases. It is not special about Windows, all consumer OSes are kinda stabilized now, and corporations do not want to experimenting and build new things.

So, I don't hate Windows, I just don't find it interesting for me. I use and will use it on a separate machine for some niche tasks, when they require windows-only software.

The fact that my game throttles when windows does update in the background as it pleases is enough reason
