MySpace failed because a better competitor came along. It had a history of predators, spammers, and viruses, and was hard to use well. (Did you see the pages people made?). Ads were one cause among many, and it's doubtful how much they contributed. For comparison, Facebook has ads, but people aren't flocking in droves to G+, and I haven't heard the lack of ads cited as the reason for any of those that are.
Radio stations certainly have ads, and those that claim "x songs without commercials!" usually put self-advertisements in instead, which they count separately. It's still advertising, just a different sort. Overall the whole process is pretty duplicitous (imho).
AdBlock has minimal market share [1], so the prevalence of AdBlock isn't an argument in your favour.
You may be correct that people hate ads, but the evidence you've given does not support your conclusion.
