Well it’s not like youtube couldn’t technically track the views even with adblockers if they wanted. The video is still being streamed after all, you don’t need the client to call another endpoint to know whether it’s streaming the video.
Google built a system that tracked video views. Users installed a browser extension that intentionally breaks this tracking for privacy reasons. Why should Google do anything? They're not the one that broke it, and these users don't want to be tracked!
Google already doesn't pay out creators for views with blocked ads, no advertiser is going to pay for ads that were never shown. The view counter doesn't matter to that. Perhaps Youtube could enforce tougher blocking of ad blockers to support creators better.
