I would like to be wrong on this and that google do not have this kind of power.
They did. Maybe not in public, but it has been communicated clearly to the employees:

I'm not saying this is okay--it probably could've been conducted in a more (politically) inclusive manner. But my argument is that this doesn't apply to the GP.
Edit. Also of course the main post about comment censoring is troubling.
For this analogy to be correct, there can be no equally populous squares. But there are equally populous squares.
So, no. One square dominates viewership (ie the town square <-> Google). You can switch to another square (ddg) if you want, but you don't get the viewership that you'd want to get the reach that you need.
While people can be physically only in one location, they do get their information from a variety of source online. Comparing Google to a town square is dumb, when you account that Facebook has much more engaged users than YouTube.
At the time of writing I'm reading stuff on Facebook, Reuters, Yahoo Finance, Twitter, Reddit and watching YouTube videos in between.(HN as well) I'm present on all of those "squares" at the same time.
