While the original comment has validity, I think it's important to know that a lot of the proton news you'll find is very "drop it immediately" biased.
I definitely think the news left a bad taste that's worth keeping an eye on, but I don't think it should eliminate them completely as an option. Especially for newer privacy advocates.
Edit: full disclosure for future readers, I may be biased as well since I do continue to use proton services and I love it. But I still try to look at both sides on things like this.
What I was referencing was the political news recently with their CEO. Lotta people up in arms about that one. However I haven't heard of the email one. Was that the one where the Users IP got leaked/turned over?
Any links you can share?
