One way out, to appease the outrage over what happened, would be for a few CEOs to spill the beans on what took place at their organizations. But after they were carted away to jail the company would still be in the situation it was before. Another would be simply to shut up shop in the USA and move somewhere else - but where? It would need to be a county where the intelligence services did not have the capability - end of business. About the only realistic and probably credible response is not to sue but to put a lot of effort into supporting third-parties opposed to the situation such as the EFF. Then at least, despite what they were forced to do behind closed doors the company would at least have a visible position and be seen to be trying to getting of the handcuffs put on it by the government.
