I love Proton’s mission just like all Lemmy users but I wouldn’t say you can trust them in terms of quality. Apart from Proton Mail and Proton VPN, most of their other products unfortunately have a deep lack of features.
I’m mainly talking about Drive and Pass. I don’t really remember as it’s been a while since I’ve tested them, but the situation doesn’t seem to have changed. Here’s a good thread for Drive. I remember Pass having problems with auto-fill which made it unusable for me.
I have Proton Unlimited but only use two of their services because of this, it’s pretty frustrating.
