CEO posted some stuff supporting Trump and his administration and how it was better for the economy or something. Got a lot of flak and it was then posted on the Proton twitter handle which was like an official endorsement. Reddit went nuts and Proton took it down with an apology from the CEO saying it was all a misunderstanding/miscommunication + “I learned my lesson” or something.

There are probably more thorough sources, but that’s the gist of it.
