Peertube is a solution, it is an open source peet to peer video hosting platform. But in truth having good competition is a way to force better practices, and if open source is the best option people will go for it if they know about it. linux, thanks to valve and Microslop's poor idea of what people want (and governments leery of Microsoft and Trump's close association decoding to have their own OS for internal use at least), have gotten a small influx of users as a whole, but with more users the more open source solutions to compatibility will be produced, and hopefully if you are looking for the YouTube equivalent you'll try peertube.
