Just like they gave up on all previous forms of cheating. Anyone clamoring that degrees will be useless NOW has not been paying attention. Until universities are held accountable for unleashing incompetent cheaters onto society, the financial incentive is to throughput as many students as possible and it has been for a long time.

And it's not just financial incentives. Many institutions are difficult to get into. They have a process and hold that process, their judgement, in high regards. If someone gets in and is a failure that reflects poorly on them. They want students to succeed, one way or another, to show what brilliant students they attract.
