Unbeknownst to most people, Paypal - and Visa, and Mastercard - are one of those monopolies that secretly hold the world by the balls: they singlehandedly decide which company or organization lives or dies based on what they reckon is a legitimate use of the money that flows through them. If they don’t like what you do, they deny you the ability to receive money electronically and there’s nothing you can do about it.
It’s amazing the power they have, and it never ceases to amaze me that nobody in power seems to be worried about it even a little bit.
