Youtube is not known as a streaming site, most people come here to watch videos, not streams. Those other sites are designed from the ground up to be streaming sites. So when people visit kick or twitch they go there specifically to watch streams, a very small percentage of people watch VODs, not to mention twitch's VOD system is kinda shit and they delete them after 60 days. I assume kick is the same with VODs.
