Been saying this for years, the only reason these companies' execs aren't in prison is because they grease all the right palms, and provide enough "studies" those greased palms can use to plausibly justify their behavior.
In the US it's illegal to imprison someone based purely on vibes, and you can't make things crimes retroactively. (See Article I, Section 9 of the constitution; in particular the parts concerning habeas corpus, bills of attainder, and ex post facto laws.)
But suffice to say, outright fraud about the ad business is pretty core to most of Google and Facebook's revenue, and the entire original C-suite of Google has at least some sort of sexual harassment or abuse story out there they never got held accountable for.
The biggest problem is not making crimes, it's that our enforcement of our own laws involving executive misconduct has continued for so long, that the statute of limitations would be the biggest problem prosecuting a lot of people today.
