I’ve mentioned this issue a few times, then “But Proton has proven to be good! It’s OK” is the usual response, that’s when i remind them of how Google also used to be good. I don’t really use a notes taking app, but in general after Google, the idea of “one login, a gazillion apps” is something i dislike in principle because even if the one central authority doesn’t go evil, one login incident and you’re locked out of everything you depend on.
Yeah, I’ll continue using Protonmail but that’s likely all I’ll use from them and diversify on the rest.
