Considering that the recent Google code leak only substantiated that Chrome is the honey pot for surveillance and data harvesting that people long suspected, even any supposedly not ad related work is technically also ad related work.
It’s something people have a really difficult time preaching logically, the veil of deception of many things. Another big example is TV, which are ad sales companies, not TV show distributors, even if they’ve successfully swindled people into a mindset where they actually pay the providers, for the privilege of being sold advertisement.
It’s really a rather interesting and eye opening segment of largely the US society that is both extremely dominant and has effectively been extremely damaging, and yet, people simply cannot see that they are like mindless drones, being programmed and reprogrammed with TV shows and advertisement.
