I’m not saying Proton was right or wrong to hand over data, who knows how much if a fight they really out up, but it seems more like an OpSec thing, where they found the account because they used that email to create a user account somewhere that they then posted about being a part of this group rhe FBI was going after.

I’d say your best bet to avoid this would be to create a free account that doesn’t have any payment info and doesn’t use your premium account as a recovery method of any kind if you’re going to use it as the email associated with a social media account. Or like someone else mentioned, if there’s an anonymous payment method, always use that.

Again, not a great look for Proton, but doesn’t really go against any of their claims as far as data encryption is concerned. Not sure if they could encrypt that payment info.

As others have said, it’s my daily driver. I like the vertical tabs, sessions, and pinned tabs. I saw someone mention you can’t watch TV or Movies through it, but I haven’t had issues with any of the main streaming sites, or the more unconventional free sites that exist, but yeah you will need to make adjustments for it to match LibreWolf privacy-wise
