Three things on Proton:

1. Proton mail has been in a rampage with sponsor YouTube channels and, in my opinion, that is a mistake. I would have kept it an organic growth, but that is me... a nobody, and Proton has become far more successful than no other email provider in the privacy world.

2. Considering even that, Proton is not vetting who is sponsoring. This is a fiasco. For instance they try to sponsor the channel "The hated one" that never takes any sponsors and even constantly criticizes channels that does it. That is a mayor blunder for Proton, there is no scrutiny at all with their marketing deployment. By the way, we learned that that youtubers get a juicy amount by Proton in these sponsorships (I think was $70 per subscription).

3. Proton, for years, has been aiming for the masses, not the most serious in privacy (for instance, androidś Proton email still uses Google push services). That is not bad per se, I still recommend Proton to many. But those with a more ideological approach to privacy or those requiring top notch on it, should be aiming for other service providers.
