I wish I could do the reverse. Could I and a million other people pay $20 now to a few law firms that could fight this without need for compensation and do everything to expose this to everyone in America?

Isn't that what organizations like the ACLU are for? Except ACLU fights for civil rights whereas your hypothetical organization fights for consumer rights. The reason why it doesn't exist is that it suffers heavily from the free rider problem. Any individual's donation of $20 or whatever is unlikely to get them $20 worth of returns, because the lawsuit is either funded or not. Moreover you'd benefit regardless of whether you donated or not, so there's no incentive to donate.

A similar idea that's immediately actionable is subscribing to independent media doing investigative journalism

hmmm that is very interesting wonder if its possible even
