Unfortunately Linux has tons of them nowadays. Google, Amazon, Microsoft are three of them that I know. And not just in kernel, but they also contribute in other projects in the ecosystem.

I remember this because Bill Gates was literally the richest person at the time but lost his position due to lawsuits like this.

I know. I am a Linux enthusiast myself. After Sadya got in the position, Microsoft suddenly became to get interested in Linux, contributing to projects and even funding them. But to this day, I still do not trust them.

My memory might be weak on this topic but Microsoft has already went through a lawsuit due to not allowing people to use other browsers. And that case made Bill Gates lose money.

OK my bad. It wasn't Steam statistics, but another statistics for overall Linux desktop usageon statcounter

Windows 10 ending support just means that you won't get updates. Your Windows 10 installation won't vanish instantly. Keeping Windows is when you change your mind or have a problem with your Linux installation, to have a backup system.

That's a good. You may still keep Windows on the side to use just in case. And you may use Linux all the time until you get really used to it. Then you may totally remove it sometime. I advise you to keep it until you're really sure.

Depends on your needs. If you use any proprietary production tools like Photoshop, you may still need to keep Windows on the side. As for myself, unless the user really gets used to Linux, gains some experience, I do not advise to switch to Linux fully. I've seen so many people who did this and returned back to Windows.
