I think there is a slight misunderstanding. The numbers from my GP were about YouTube subscribers and views, not PeerTube. The point being that this is a minuscule YT channel that is moving to PeerTube, one that is hardly representative of anything.

For comparison, here [0] is the YT channel that has moved to PeerTube, and here [1] is a random musician's channel that I happen to follow. The second is many times larger, even though it is a single person's channel.
