I think you're extremely confused as to what Proton is and the service they offer.

I also think it's because you're falling (or have fallen) into the tribalist view of "if you're not with us, you're against us, and if you're against them, you're with us".

Proton is a-political, pro-agenda. Their agenda is "net neutrality, privacy, security". They don't care who makes that happen, and will support anyone who fights for these things.

They won't take an antifascist position because that would put them on the political spectrum.

I also understand that - to you - not making that statement already puts them on the political spectrum, in the opposing camp, but that's, again, due to the tribalist views.

They've praised left-wingers and right-wingers, they've criticised Democrats and Republicans - as long as anyone pushes for their agenda, they will praise them, as long as someone threatens their agenda, they will criticise them. That's all there is to it.
