It's not hard to see why, either. Transcoding video is expensive. To deliver a YouTube-like experience you have to be certain that each user will be profitable somehow, something that is easy with ads but hard with any other model.

free for small usage, typical cloudflare fees for large usage. very reasonable either way.
