What are the ethical responsibilities of companies that stole music from creators?

So, the companies that stole human made music in order to make money off of people who go to their websites and pay for the services, do they have to give that money back to creators somehow?

Is it possible that the ai music bubble could pop once there’s a class action lawsuits against these companies, or whoever buys their data?

What would happen to all these the prompts that people have saved? Would they disappear, or could people still download the files. And if they can do that, are they opening themselves up to individual law suits in the future?

I know an artist with a lot of resources that has said in no uncertain terms that he’s excited to sue ai creators. But should we be more focused on the bad actors and companies who steal from artists?

Of course, as of now ai works are not included in the copyright protections law, so I guess that means they can’t really compete in the market anyway.
