My theory is that "AI" doesn't really have any long term paying customers and the majority of the "users" are people who have cooked up some clever hack to effectively siphon computing power from these providers in an effort to crank out the lowest effort ad supported slop imaginable.
Every provider seems to have been plauged by these freeloaders to such an extent that they've had to develop extreme and onerous countermeasures just to avoid losing their shirts.
What's the word? Schadenfreude?
