Oh yeah, I'd love to go back to playing whack-a-mole with advertisers. I can't tell you how grateful I was when someone finally came out with ad-blocking software with regularly updated lists. Thing is, it's much more complicated nowadays, what with beacons, trackers, analytics, evercookies, etc., than when you were blocking banner ads on simple HTML pages. I actually know how to write a regex, unlike the vast majority of mankind, but I sure as hell don't want to spend all my time trying to block all this crap. You might as well tell everybody to develop all their own software. Do you really think anyone who can't write a regex should be stuck seeing ads?
I agree, though, that ISPs shouldn't be involved in deciding what content you receive. After all, aside from the slippery slope, there may be some perverted individual who loves ads.
