That's an individual solution. I'm interested in a world that's as good as possible not only for me, but for the other people too. Most people around still use Google. They might find this new feature useful and start using it, and possibly suffer this bias. Not only they may get manipulated individually, but it can have broader consequences, even to those avoiding the feature. If Facebook can influence which president get elected in a country, it will also affect people avoiding facebook (sometime for this very reason).
Avoiding stuff for oneself is a first step but it's hardly a solution, these big corporations have a non negligible effect on the world, still with you as a member.
We'll have to start to raise awareness around these things, in addition to all the subjects on which we already need awareness.
But same old same old I guess, Google already puts you in a bubble, just even more concerning I guess. It was manipulating us, now it's another, new, potential manipulation angle.
