They arent really trying to make the site unusable with adblocker they are trying to bypass adblockers which is fundamentally different. And they gave up months ago theyll go at it again sure but for now they arent doing much about it. If they trully wanted to just disallow adblockers they could and it would be trivial, there are plenty of websites that do it certainly google could figure it out but they dont because that would push away a subtantial number of users and clearly those users are still worth having even if they are not seeing ads, presumably because of the data they are still harvesting and the numbers number of users and the word of mouth.

anyways maybe u should stop licking the boots of fucking google of all companies and make a real argument against adblockers like that it actually meaningfully hurts smaller websites, because not only would i not give a shit if youtube went under somehow i would be fucking dancing in its grave.
