Is this similar to how Mozilla is set up?

First of all, I did not say that proton is opposing capitalism. I said that to oppose capitalism does not mean you have to be opposed to free enterprise. As in, you can be opposed to an economy comprised primarily of capitalist institutions without being opposed to the concept of free enterprise. Proton is simply an example of such a business, which can be used as evidence for the fact that it is entirely possible to start businesses in a free market economy which are actually interested in solving problems as opposed to using the existence of problems as a vehicle to enrich a class of shareholders.

Second of all, “it’s filling a niche created by other companies’ poor privacy policies” is essentially nothing more than a restatement of the second sentence I wrote, which I will repeat here: “I pointed out that as long as it’s a for-profit corporation, it would have not have any financial or legal incentive to continue pursuing its mission if it ever achieved a certain level of market share.”. You’re right that them adopting a nonprofit structure doesn’t change that, but it does change their ability to sell out their customers at the discretion of a class of shareholders, unlike any business which is owned by private individuals.

It’s https://port87.com/. I’m still working to make it ready for business use, but it’s ready to use as your personal email. It’s really good for keeping your email organized, which is something I’ve always struggled with personally.

It’s behind a waitlist right now, but I send out invites about once a week.

Hopefully not in the EU.

I think so. Initially it was pretty rough, but they've been actively improving things, so it's better now. Once they finish implementing labels (soon?), I think it'll have everything I need.

Some downsides:

• must use their client - not an issue for me, but could bother others; their app isn't as nice as proton's IMO
• no extra apps, just email and calendar
• no good way to export data - they're improving this, but it's still a pain

The reasons I switched are:

• cheaper family plan - I'm currently the only one on it, but I could add more accounts for €3/month
• 3 custom domains - I currently use two, one for family and friends, and the other for online spam; I could probably use aliases, but I want it to be easy to switch if Tuta does anything I don't like; I'd have to get the top Proton tier for that
• I didn't actually use the other services anyway - I tried the VPN, but I honestly prefer Mullvad anyway, and I don't need VPN always right now

That said, Proton ultimate is a decent deal if you commit for 2 years. I just decided I'd give Tuta a shot and they're pretty reasonable.

I DIY it with my custom domain.

Probably something about toenails
