These two cancerous clickbait entities were basically 95% of the sole reason I started using adblockers to begin with many years ago. I can't stand seeing their crap on any webpage I visit. It is filth that ruins the Internet for majority of people who don't have a mental filter to not click on this stuff.
The other 5% reason is malicious ads/tracking. I'd actually be open to not running adblockers anymore if these two reasons were eliminated from the web. I'd be fine with small non tracking ads from non cringe worthy gigantic ad networks that invade basically every webpage I visit nowadays.
PS - Ublock Origin actually doesn't block these two networks (Taboola/Outbrain) by default - you have to enable Fanboys Annoyance list to do so.
