I fear the courts will side with the tech companies on this as regardless of how illegal or immoral a certain act is, if you do it on a large enough scale it becomes “okay” again in the eyes of the system. Genocide, large scale fraud, negligent financial actions, pollution/poisoning, etc. You dump toxic chemicals into one person’s cup and you get the book thrown at you. You dump toxic chemicals into an entire city’s water supply and you pay a paltry fine that is never enough to seriously damage the company because that’s bad for the economy.
