If you main issue is the need to download apps from the Play Store, consider Aurora Store.
I suggest Droid-ify over the F-Droid store for ease of use, but both work fine
Definitely do! I also suggest Droid-ify for FOSS apps :)
Been using Proton for over 4 years now, and have had no issues with it. I don’t use folders or tags that much, but if you are a paid member, you get unlimited of those. They recently announced calander invites (I personally never want to use them) and it looks like it should work fine. Proton also has unlimited aliases to hide your actual address, which I use all the time (coming over from SimpleLogin.)
The bundle (mail, VPN, calander, pass and drive) is really bang for the buck for what you get, even though you don’t use some of them. You can always upgrade to it later if you wish. And in case you don’t plan on paying, the free versions work just as you expect!
If you have any questions, just ask!
Waterfox was bought by an ad company.
Edit: According to this page it’s no longer the case, though I still am not completely comfortable with it.
I hate that most people don’t want to care for convient’s sake… “You’re only making your life harder for yourself”. I simply want to be in control, not the corpos.
