I'm not going to change from Proton because of this, but what you're suggesting is probably not a bad idea. CEOs are and should be easy to replace and mistakes like this are pretty standard reason why CEOs get booted.
edit removed some rather incriminating, unverified claims about Andy Yen
I think you need to be in Proton's Board of Directors to have any effect on this. Perhaps if some of those guys are your friend?
