Why google is so desperate to show YouTube ads and forcing all the browsers to adjust with them

I think the rise of AI usage have already started massively decreasing Google search users. And this will keep decreasing. Traditional search engines doesn't have any future at all at this moment - they'll only be used as link directories. Like when somebody needs a list of websites about something, then they'll go to search engines to collect a bunch of links.

But the social platforms are evergreen, whether it's social circle based platforms like x/facebook or video platforms like tiktok/youtube. They aren't going anywhere in near future.

So, google's only big revenue source remained is Youtube. They'll have to find a way to make it profitable. Last time I heared about youtube income - it was on the burning side. So it's clear why they're so desperate to fight against adblockers and other related stuff.
