To be fair, the monetization of "free" content should be done different way: utility payment model is the way to go. YouTube Red got it right, they just haven't pushed it all the way - eliminate ALL ads. Apple Music and Spotify got it right too.
As a customer, I have fixed amount of hours to spent in a day to consume content, so content providers have to compete for this time to get compensated. If you pay flat fee at ISP level, then it can distributed to content owners minus platform service fee. This way you don't stuff people with gazillions of non-relevant ads and there's natural flow to get higher quality content to attract customers to your site.
Ads are not needed to get "free" internet.
