I think this is the same concept as how people will gravitate in a city to have the worst possible commute they can bear because most people value having a nice home and a nice job over a nice commute. In a similar way services will inevitably be crammed with ads until it starts to negatively affect profits, because people value the content and publishers value money more than either value an ad-free experience.
To stretch the analogy, ad blockers are people who drive in the HOV lane without paying. It isn't so bad that you do it, but if everyone did it the system would break. I personally block ads out of principle because I believe we can transition to a micropayment model and blocking ads forces the issue.
That being said, can anything really ever save us from ads? From my logic in the first paragraph, Patreon et al will eventually be as ad-infested as anything else. Maybe the fundamental answer is to consume less content.
