There is a difference, though, and I know why those pitchforks are raised.
YouTube is a video service behemoth, and it is owned by Google, a Big Tech company that has little respect for its users. It is one of the last things most Lemmy users (known on average for their hate of Big Tech, hence why we don't have this discussion on Reddit) would want to support.
Many of them would, and some do, support alternatives. But there is just nothing to the scale of YouTube, which exacerbates the problem as users often have nowhere else to go. And so they will do their best to use YouTube in a way that gives 0 benefits to Google, and will only be happy to see this giant fall and replaced by something more user-centric, free from corporate control, and privacy-friendly.
