Google is blackmailing the Blender foundation to try and get them to enable adverts.

edit - and Blender have now got https://video.blender.org/ in testing already. I didn't think they'd be the ideal people to issue ultimatums to on video hosting, given their technical specialities.
A situation like this triggered the development of git, (after the licence to use bitkeeper was withdrawn from the linux kernel team) so I will be watching the fallout with interest.
The Blender team never did that, and also never reacted to any youtube support mails.
They said YouTube was requiring them to enable ads, but the ads checkbox was grayed out. Among other issues. Not that they wanted to enable ads on a not for profit site. But just taking this one issue, it's not clear how they could have possibly complied with Google's requirement, when Google keeps the checkbox UI element grayed out and unchangeable.
If you're right 95% of the time, you get a discount. If you're wrong 50% of the time, you pay the full fee.
Who would be in charge of setting these?
