Precisely. Youtube is a hosting service first and foremost but increasingly it is used as the propaganda arm of some of the most despicable entities in politics who are aiming for the audience, not the hosting as their main reason for dumping content there. They are freeriding on the youtube brand and do incalculable damage to some very precious concepts and societal structures.
You can't though. Bitchute was banned on Twitter for a long time. The barriers to entry for a new competitor, including network effects in addition to hostility from other platforms, is incredible. YT have a monopoly in their domain.
