Server costs are higher for video, but it's called PeerTube because it uses peer-to-peer technology so that when people watch a video they also send bits of the video to each other. This significantly reduces the amount of bandwidth the video host needs, which makes it better suited to indie servers with lower budgets.

I don't think it's aiming to be like Telegram or any messaging service. It's mainly meant as an alternative to YouTube.
