Your comment reads to me like a criticism of lesswrong, but the linked article is entirely about the political axis of a potential technology. Am I misunderstanding your comment?
Look at the Patriot Act, or any other military censor you choose. Same concept - we need to peek into people's private communications to determine if they're a terrorist! We need to scan their photo gallery to prevent them from abusing children! All are means to the same ends, the state wants to enforce absolute loyalty by sucking out any room for protest. Throughout history you can very easily ascertain that authoritarianism isn't restrained by a lack of mind control, for every life Oskar Schindler saved there's another 1,000 bodies buried in Babi Yar. The fact that ESP might have prevented those 1,000 lives from being saved somewhat glosses over the millions that were ostensibly genocided without using psychic domination.
Then why did you start this thread by complaining that technologists ignore the politics of technologies?
Their "Nazis with a mind reader" scenario explains it perfectly; only a small minority of people were able to lie well enough to escape a regime with 1940s technology. Millions of other people were killed and the Nazis did not need a mind reader to find them. A modern authoritarian state with a mind reader is barely any scarier than a modern authoritarian state without one.
My brother in Christ, the call is coming from inside the house.
Today and in the Nazi era, there were functional social controls that served the same purpose and achieved, very clearly, dangerous results. No mind reading was necessary.
