i am not the most tech-savvy of this anti-site but the main issue with just going ahead and hosting your own video sharing and posting site is the size of the files and the actual cost of hosting the files and the site, right?
is there no way to compress video without fucking decimating the quality and even if there was, would this even be a fix?
yeah video storage is really costly and hard to do at large scales, and if you're streaming video there's a whole additional set of really difficult things to deal with. like, all the big platforms with streaming video have CDNs (https://en.m.wikipedia.org/wiki/Content_delivery_network) which reduce latency by having the video sent from somewhere physically closer. there's a reason there's not much in the way of real competition for youtube. you'd need a massive amount of capital to start and even then there's no guarantee you'll get an audience because of network effects. if no big creators upload there, then there's no viewers, and if there's no viewers there won't be a motivation for creators to upload there. even microsoft couldn't launch a twitch competitor after paying the streamer ninja an obscene amount to use it
