I haven’t seen their governance structure yet, but I don’t think it will ever be like Altman and OpenAI. Eugen just doesn’t have that cult of personality around him, and there’s not that much money in a free and open-source platform that doesn’t lock people in.
And HTTP/2 can be used to provide video steaming, but that doesn’t mean that nginx will be the next YouTube. This isn’t a question of technical feasibility, but project focus. Though, I must admit, I don’t follow the development of fediverse software all that closely, so maybe it is on the roadmap.
