I mean, sure but we are past that. No large YouTuber will give up getting paid, and go to a system with a much smaller user base so even stuff like affiliate links and sponsorships are worth less. Basically double lose money just to join peertube. Especially since most large YouTubers have a team of people who they pay, so they cannot afford for their employees sake to take such a large loss just to support peertube.

More likely this leads to Vimeo, or like twitch TikTok or something else being able to support a normal video platform than it leads to people using peertube.
