I'm not 100% sure, but I think you can get paid for blowing the whistle on these guys. And I think you can do it anonymously:

If this doesn't exist, they should have this anytime the gov't puts out so much money to rescue the economy. But to be honest, I'm actually not sure why they didn't just let the companies lay off the employees, and just use the unemployment system to tide people over until the pandemic ended. Giving free unsupervised money to CEOs and small business owners just seems to me to be asking for trouble.
