That’s almost always prohibited.

Given the current administration’s recent market behavior I would not be shocked if people got away with exactly what OP described.

It's often prohibited by contract, not just law, so what the administration thinks is only part of the story.

Of course whether or not a contract is or is not enforceable as such is also a matter of law. As I understand, this IPO was unique for a variety of reasons. The fact unique terms are promulgated in a contract does not mean (at least in saner times) that they are automatically immune to regulatory scrutiny.
