It's called "cloud feudalism". Amazing how accurate that term is, during feudal times, the king was free to change their terms, and if you disagreed you could shut up or get out of the kingdom, which was a difficult process and meant cutting off ties with people and business partners (or letting them know about your change of address). And if the king said "You, you did something I disliked, out!", you could protest all you want but that would fall mostly on deaf ears.

Of course "deaf ears" is nowadays support emails being handled by copy-pasting bots.
