Fully agree, responsible parents should not allow their kids (including teenagers) to use Shorts or TikTok. It is a shame that YouTube does not support blocking that crap. It is obvious "Don't be evil" is not Google's motto anymore.
How about possibly also failing for being too US centered, basically being an "internet portal" but mainly for the US. Sure Yahoo where _huge_ 2000, but it was never the main goto portal in Scandinavia where I grew up using internet from the mid 90s.
Here Altavista was the defacto standard for search until Google replaced. For the portal aspect of Yahoo, there were local alternatives with more relevant material.
Of course it possible to limit the number of virtual threads. A web server can have a limit on number of virtual threads too, and queue incoming request before dispatching to to workers (virtual threads).
As other have said, this can be achieved with a semaphore and the bulkhead pattern. You can also limit the number of number of connections.
I would expect any "production ready" web server using virtual threads having some sort of limiting. That must be the case right?
