I think the other tactic to defeat Google is to click on EVERY SINGLE AD you see. It will destroy their ad tracking capabilities and it will also destroy their business since they won't be able to tell what is a good click and what isn't. I've started doing this and I don't think there's anything else that can get them to stop actively violating our privacy.
Let me pay for my Gmail account. Let me pay for good support instead of automated decisions and getting kicked off the platform with no recourse. Otherwise I will render myself useless to your algorithms by changing my behavior so that algorithms won't be able to make sense of it.
