I can't really understand the outrage. YouTube is a private company, not a guaranteed free speech institution.

It's like trying to place an anti-Google ad and getting rejected.

I'm not even sure if this is protected by anti-monopoly laws. Perhaps if you want to advertise your own product, then yes, but if someone, out of the kindness of their heart, wants to advertise a competitor's product, is that protected?

I agree the status quo is not great where we rely heavily on platforms like YT, X without any guarantees of availability etc. and we should change that. But that's not at all news...
