This is why I expect the video side of things to be more on the level of stream channels that self-host content with subscriptions for access to VoDs, rather than singular big platforms. Streaming in of itself is a lot of traffic too, but you have much bigger RoI per bandwidth spent with live viewers, and you cut down the storage requirements with limited VoD access too.
The only problem then becomes discovering these channels from the rest of the federated space, but honestly, either that will be a problem that will be solved by the space in a more general manner (oooh, imagine the return of web rings! Lol) or… It will end up being an issue that doesn’t matter. Like right now, still coming from video games, MinnMax and Second Wind are two creator-owned platforms that appear to be relatively unpopular, with short amount of thousands of views, except they run off of donations on Patreons and the viewers they do have keep them afloat with a good decent margin.
