I think the reason is not sensitivity, but that it's less risky to move a very new, niche service if they fuck it up somehow. as I understood their announcement they may move other services too later on

Well, Proton can move wherever they want and be as good as they what, I'll never be a customer again because of what their fuckhead CEO Andy Yen said.

I don't care that he's backpedaled, I don't care that Andy Yen isn't Proton-the-company, and I'm even willing to accept it was a very unfortunate duh moment on his part. Here the thing: I don't have many ways as a nobody to get back at Trump, but one way is to not give any of my money to anybody who enabled him, even by mistake.

So Proton is on my shitlist forever thanks to Yen.
