Like PayPal, GFM can arbitrarily freeze the accounts of anybody they don’t like. (I know this to be a fact because PayPal froze me for two weeks for absolutely no reason a number of years ago. I no longer do business with them.)
Why would ANYBODY entrust them with their money?
Forget facebook all the other tyrannical platforms out there. Create your own site using a like minded provider. Want donation, have your supporters use zelle to place money into your account. These large platforms are not needed
Give send go and Venmo seem to be OK, FOR NOW!!!
