I’d guess mostly because of the storage space and processing power needed. I run my own Peertube instance for personal videos, and it’s quite resource intensive due to transcoding (making the 480p/720p/1080p quality options). These are needed for a smooth viewing experience, especially on mobile or slower internet connections, otherwise you’d have a lot of buffering waiting for the 1080p file to load. But creating all these different quality versions takes up a lot of space and a lot of processing power. And processing power and space requires money to keep running.
This. People do not realize what goes into running a media server. On the fly transcoding is so resource intense. Especially when you consider you could be doing it for many different streams at a time. Then you look at storage for it all and you need a massive amount of drives to store it all. Then there's just the bandwidth necessary to run multiple stream constantly. The reason there aren't any decent competitors to YouTube is almost entirely because of the resources needed.
