TL;DR: Proton complied with Spanish authorities and gave up all the information they had on a man (the recovery email.)
With this in mind, I would personally say Proton is safe. The fact that all they were capable of providing was the recovery email should show that Proton is trustworthy with their privacy.
This is only one case, if anyone has any others, please do share them.
I don’t like the usage of Chromium in general, but it is open-source, so I don’t think the usage of it is necessarily a dealbreaker, considering it’s not the same as using Chrome. As far as I am aware, Vivaldi is not fully open-source, but generally has a good reputation.
