A provider having more than 50 users and offering more than one service doesn't make them evil. Use Proton. They are the best, and they're not likely to disappear. If you intentionally seek out small services because you think being an underdog is some sort of privacy merit badge, you'll get "absolutely fucked" over and over again.
Also, you should consider paying for the products you use to encourage sane and user-friendly business models. But that's a different discussion altogether.
