Until you realize that there are around 2 million active users on the Fedi. That means even IF a video gets 6000 views. That's still only 0.3%.
And yes, of course that person didn't get their video out in front of 2 million users. They probably only got it out to a few hundred who shared it, but that's not the point. Even if that video was shared 40,000 times, that's only 2 percent of the Fedi. The point is that the majority of the people on the Fedi don't use PeerTube.
