Ad block extensions work great on browsers, but not on phones and other streaming devices. And I couldn't even get a ad blocking DNS to work either...so I bite the bullet and got a Premium subscription. Money well worth spent on never seeing any damn political ads!
Yeah, YouTube has gone down the toilet with ads and they don't care. I use Chrome so I use a combination of adblockers such as Adblock Plus, Adblocker Ultimate and Adblock.
