Advertisers need to learn that the more obnoxious they get, the more we will tune them out. Simply continuing to dial things up with all the crap they have pulled on the internet is actually counterproductive.
I'd say the ability to block ads is a good thing on the whole.
I used to go to a (completely unrelated to photography) site that had the most obnoxious, click-baity ads. Every once in a while the site owner would run a "housekeeping" post where people were free to bitch about the way the site was run (normally forbidden), he'd get a dump-truck-sized earful about the ads, act all genuinely surprised they were that bad, swear to fix it...and nothing would happen. (There were autoplays that would start when the page loaded; start again when you replied to a comment, start again when you went to the next page, start again when you commented...and there were ads (fortunately not autoplaying videos) that verged on X rated, too, in re: enhancements to certain parts of the male anatomy.)
