I personally feel like this is overblown way too much, if I'm not missing anything.
While the wording could have been better, the CEO clarified later on that he specifically talked about the nominee and criticized democrats in position of power that blocked bills that are important to Proton's core values.
I understand that the initial post could have been read as a broad support for Republicans and their general policies. But with the clarification it is, in my opinion, very possible that this is exactly what was meant.
Obviously it also wasn't great that he replied from official accounts. But again, that's more of a PR problem and less of a core value problem people make it out to be.
Why use the word "claim" for something that's painfully and obviously true? ๐ค
