Google has been relatively "good" to us, the users, so far, and they've even been our allies in some cases(SOPA, ITU).
But make no mistake, when the Internet will start a trend towards fully decentralized/more anonymous services, they will become our enemy, because that will endanger their very way of making a revenue.
If I were a Google boss I'd try to start making money from other business models besides ads as soon as possible, possibly from hardware, like Apple. I think they're already planning this to some extent with Motorola, Google Glass, and even Google Fiber. But they need to hurry up. That trend might arrive sooner than they expect (within 5 years).
Facebook is already dead. They just don't know it yet (it takes a while for the market inertia to stop).
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.
BTW why a rise of anonymous private communication would mean an end to the existing web, as indexed by Google? A lot of things are still perfectly OK to do in public. Consider open information sites as Wikipedia, most business information sites, and even most online commerce.
Google makes its money by being a directory service to the decentralized internet. Centralized services are at best neutral (G+), and at worst a direct threat (Facebook).
The first thing anyone does when they want to use a darknet-style web is bookmark a directory service. If decentralization ever becomes popular enough, that's just reason to create "google tor search".
But make no mistake, when the Internet will start a trend towards fully decentralized/more anonymous services, they will become our enemy, because that will endanger their very way of making a revenue.
