They probably will, it's too dangerous to take on US clients these days. I believe perfect money recently did they same thing, and closed all current active US accounts.
Let me quote this excellent piece from an article I read recently:
"Never do anything against conscience even if the state demands it." - Albert Einstein
To effect change we are left with a boycott in everything but name. It means that non-US Western businesses need to start using "not subject to US law" as a marketing point. We need cloud providers and software vendors that don't have a US presence, no US data centers, no US employees - no legal attack surface in that nation of any kind. Perhaps most critical of all, we need a non-American credit-card company.
If enough of us start to pull our technology purchases out of the US they will indeed sit up and take notice; money leaving the country may well be one of the only things that will ever cause them to do so.
