Andy Yen's values are incompatible with Proton's mission. He advocates for poor security practices, supports fascists, and he verbally abuses his subordinates. As such, I can no longer in good conscience continue to financially support a company with such terrible leadership.
Unfortunately for me, my subscription just renewed last month on a multi year plan, but it does give me time to browse for and experiment with alternatives.
If you're able, I encourage you to do the same and cite Andy Yen as the driving factor for your decision. We can't let these tech bro fascists destroy what little semblance of privacy we have left.
A lot of the past criticisms of proton I believe are very overstated but it's clear that things are not healthy inside proton.
Edit. Considering how big of a target proton is, if this is how unhealthy the culture is, I'm surprised they haven't had any big incidents already.
