What this guy's doing is shameful, but I've seen dozens of otherwise lovely people, working for charities, spending much more time on socially-important and useful work than 90% of the crowd here... and the same people would push barely legal (if not illegal) targeting on masses of people, arguing to push cigarette ads in markets that still allow it. Advertising is cancer and the current model is not sustainable.
What I'm (poorly) trying to say is: be angry, let everyone know that you're angry, make more people angry, but remember that focusing on this guy is a distraction from a bigger systemic issue and it actually helps organisations like Alphabet.
