Unless the SEC or FEC or Anti-trust get involved, it won’t.So Paypal chooses who can and can't use them? That's gonna bite them in the back (it SHOULD).
Even if I was willing to completely give up all internet transactions, even some physical retailers either use Paypal directly or use another service that resolves through Paypal. That’s why they can even do this in the first place.
They have such a hook that the only way to 100% avoid them is to basically go back to pure cash, and at that point, you’ve just voluntarily imposed the same thing they’d want done to you for having the kind of views that would lead you to boycott in solidarity with Molyneux in the first place.
