They started blocking users with advanced adblockers completely in some places. It's expected they'll roll out that policy in most countries. Prepare to either ditch Youtube completely, watch dozens of ads as well as sponsored segments every couple of minutes (because why would Google pay content creators who make them a huge pile of money by providing content for free adequately, right?) or pay hundreds of dollars a year. Even then they might start showing you some ads because why the hell not? Big tech stole the internet from us and now they're banking in on it big time. Needlesly to say this is not a sustainable business model, but since when did that ever bother mega corporations?
