Your IP address is public so every time you consult a website, there is a number of actors (in addition to the final website) seeing your IP in their connection logs: ISP/routers/trackers/CDN and more. PeerTube is transparent about it: we warn you that if you want to keep your IP private, you must use a VPN or Tor Browser. Thinking that removing P2P from PeerTube will give you back anonymity doesn't make sense.
It can also be displayed on external websites to promote your instance, such as <x id="START_LINK" ctype="x-a" equiv-text="<a target="_blank"href="https://joinpeertube.org/instances">"/>JoinPeerTube.org<x id="CLOSE_LINK" ctype="x-a" equiv-text="</a>"/>.
In theory, someone with enough technical skills could create a script that tracks which IP is downloading which video. In practice, this is much more difficult because:
It will delete {count, plural, =1 {1 video} other {<x id="count"/> videos}} uploaded in this channel, and you will not be able to create another channel or account with the same name (<x id="PH" equiv-text="videoChannel.name"/>)!
