It's been illegal forever to run a pirated copy of Windows or Photoshop. Even 30 years ago people weren't worried that their pirated copies would tattle on them, businesses did not use pirated copies because vendors would report them/not work on their systems, legal discovery could find them, etc and then they would get ridiculous fines.

It's one thing to get a copy of "illegal" software and use it yourself. The stakes are basically zero and you almost certainly will not get caught

It's a completely different thing to run a business on it with dozens of employees and requiring the employees to break the law to do their job.

Completely different to run a business on massive copyright infringement. A business like... OpenAI.
