The point is to avoid a Stasi-like spying future and to CYA. What if the official "PC" public opinion changes in 5 years dramatically and a witch hunt starts on anyone expressing a certain opinion that was considered normal in the past? Look at what happened to Brendan Eich. So officially you can generate "approved" traffic by visiting "safe", publicly endorsed and usual established sites and in private you can browse whatever you wish, e.g. discuss political issues without a fear of repercussions, invent a new science that would pose problems to established ones and group with similarly-minded people as much as you wish without blowing your cover. Frankly, what I am doing is none of your business if I try to adhere to the golden principle as much as I am capable of; I don't need my biometrics taken by Facebook, stylometry learned by Google, coding style footprint generated by GitHub , my online history stored by my ISP, my opinions revealed by Reddit etc. And for your point - I am sure we hear only about the "stupid" ones that made a silly mistake; we would never hear about the clever ones that can restrict themselves when they don't have 100% control of the situation. They do exist. And most men can't even spot clear signals when their wife is cheating on them, not mentioning the ones that can blend in perfectly... Often the balance of power is achieved by secrets the ones in power know on each other via MAD, so when there is no deviating data, there is no secret to crucify you for.
