I think this gets at the licensing issues and the "non-commercial" sentiment of that type of usage, whether it's explicitly CC-NC or otherwise. Notice the "Buy me a coffee" link. Is this considered "for profit" now? This person is asking for donations and is effectively monetizing the videos, at least is a very weak sense. And thanks for that 'overlays' link. It's clear these types of sites only exist at the discretion of YouTube. That's unfortunate and all the more reason to try to enrich the commons with more CC0/CC-BY/CC-BY-SA work.
