The ones that are so offensive to Hacker News commenters that they will rail wildly against them, call YouTube’s business practices scummy because of them, and make a new hobby of blocking them rather than pay $14 a month for YouTube Premium.
Such a snobby comment. Do you really think people on HN don't know uBlock Origin?
People make their own adblockers because YouTube and uBlock Origin have been in an arm race for years. Sometimes uBlock Origin doesn't update fast enough to respond to YouTube's changes.
