The lies and dishonesty come from the highest authority in Google. The only real solution is to force the dissolution of big tech and create competition once again. The only thing that can change business behavior is effects to profit.
If you really have never heard of this type of thing occurring, then you are either willfully ignorant, or completely separated from the reality of how business is conducted with Google. I don't say this with malice, but with plain honesty. This is a fundamental part of how the interaction with Google works. To deny this so plainly can only make any sort of sense through sarcasm.
Working in Ads at Google, this isn't something I've ever seen. If you're able to share details of cases where bribing insiders has happened (either here or to my email) I can look into them?
This hardly seems like a productive sentiment. A system is only as corrupt as the people in it, and this person is openly trying to address a specific problem the best way they know how. Why would you try to dissuade them? I don't understand what your end game is except to make Google more corrupt.
