I agree with your point, but think your wording sidesteps the issue. Google has been our allies because the same things that we were against (IE a closed internet) directly endanger their revenue. They won't change their attitude when they see a huge threat to their revenue, although we may notice that their motives have always been revenue, and that does not necessarily align with ours.

Additionally, I'm not sure decentralized/anonymous services are necessarily a bad thing for Google. At the moment they have alot of competition from site like Facebook, and online shops and such. However, they are still the gateway to the internet, and are probably in the best posistion to continue to provide targeted advertising in the new age of anonymous internet. Consider the value of having your shop get a prefered listing everytime someone searches for shoes. The value of this would go up when your ability to do directed advertising through other means goes down.

Also, even with anonymous services, information still leaks, and the larger you are the better you can take advantage of it.
