Depending on which part you asked about:

1. Yes.
2. Yes.

Also, as a non-american why would I care until Proton product is good?

Two things:

1. In the worst case, where they support fascists, they’ll also likely not provide the protection from fascists that a lot of users are expecting and paying for. E.g. trans people might be using the service to protect themselves from an administration that is trying to erase them. Will the service actually be safe for them? Can people trust that fascist supporters won’t break their own product to support fascism?
2. We’ve seen lots of cases of tech companies and CEOs having a deleterious effect on politics. Is this a sign that proton will be yet another of those companies? Swiss law seems to work in our favour here, but if the company is rotting from the head, it won’t be enough.

It could be that this is just a series of clumsy actions from the CEO (including using his birth year in his new Reddit nick, when that birth year is also a well-known nazi dogwhistle (88, code for the 8th letter in the alphabet, as in HH, as in “Heil H…”)), it could be him showing his true colors.

As an existing customer I’ve taken a sort of wait-and-see stance; I likely wouldn’t become a new customer right now.

They shouldn’t know directly, but they can still be informed by public discourse whether it seems like they have a majority normal users with some creeps thrown in, or if the only circles discussing and promoting their services are nazis, or etc.

So yeah, it’s not a 100% identity between the two, but the point remains that the actions of the owners / operators will influence whether they’ll be interpreted as openly running a nazi bar, or trying to run a normal bar but struggling to keep cryptofascists out, or something on that scale.

Privacy focused services will generally be sought after by nazis, illegal arms dealers, CSAM dealers (but I repeat myself). But like with the nazi bar analogy, they need to handle it properly and take certain stances to avoid that group becoming their only customers—and the rest of us blocking it.
