ELI5: Why hasn't Youtube tried to remove Adblock?

They get their revenue from ads, which come from viewers, which come because YouTube is, by far, the favored video sharing site.

If they block Adblock then those users leave so the content creators are encouraged to leave and then the other users leave.

Allowing a small percentage of adamantly anti-ad users to view the site without ads winds up hurting them less than trying to force them out.
