You do not assign your copyright to Google in order to publish your video on YouTube. That will not hold water. Rather, you declare Google an irrevocable license to use and publish your video on their platform.
I think what GP was getting at is that people will rip and re-host other people's videos.
That already happens plenty on Youtube itself, so I don't think it's crazy to assume that you'll start to see PeerTube instances that take someone else's channel and just mirror it.
Now, is that PeerTube's problem? Not really, it's between the copyright holder and the uploader. Is YouTube going to try and raise a fuss? I kind of doubt it, the press would have a field day pointing out the hypocrisy.
But the laissez faire attitude of content creators (and Youtube as a platform in general) might ironically make it attractive to hosts who want to fill up their instances with content quickly.
