Why do you say that?

I don't think the Youtube product managers really care enough about Vision Pro to prioritise making an app for it. That doesn't mean they strategically disgree with the product and actively wish to hamper it.

Indepedently of Vision Pro, I think they just might not be that enthusastic about third party youtube apps.

They explicitly opted the YouTube iPad app out of working on vision pro

Maybe it was a UX bug that hampers the experience to the point that where the website is a better experience, and they felt that a bad app would hurt the brand more than no app.

Or, maybe there wasn't but they didn't care enough to test so they disabled it 'just to be on the safe side'.
