By your own logic, Paypal may decide not to be associated with anyone based on any random criteria, including opinions, race, sex, age etc. It can be black and white, of course, just not today.
No, state and federal law explicitly create protected classes, and describe the scope of protections granted. A service provider would be opening itself up to huge liability if it cut someone’s service based on, for instance, race or gender.
You are missing the point: PayPal does NOT provide any specific reason for the termination, so there is NO protected class as you cannot prove they terminated an account for speech, race or gender.
Giving no reason, absent a contractual or legal requirement to provide one, falls far short of offering up a blatantly illegal explanation. Even so, companies have clearly been found guilty of illegal discrimination, even when they went out of their way to hide their unlawful motivations.
But not political stance? Seems a glaring oversight. Unless the people who wrote the regulations like being able to request a payment processor shut off campaign donations to any newcomer with better ideas than them.
But that would make them beholden to the business interests that actually control the money, and leave them helpless to enforce any real regulations on the same. Surely no elected representative would be so shortsighted ;o)
