I think you are over-generalizing. As an anec-datum, I made this point to someone in 2014 (that FB makes about $25/year/person)and I asked if he would pay $25/year. He said he would pay $25/month. And this is definitely not someone who is going to be bothered to learn anything about installing adblockers. He just happens to be reasonably successful in his non-tech field.
