This already exists, e.g. invidious.tube (YouTube proxy instance) or wago.tube (PeerTube instance).

Create it and before opening it publicly, squat you.tube and make it randomly redirect to any other registered domain.

Would probably violate trademark law and icann would make you give it up. I guess if you go opennic or use a different alternative root they might not care about court-ordered domain forfeitures.

You could probably get away with never releasing it and just leave it null.

Or simply hand you.tube to YouTube. Why not? :)

Where's the fun in that

Put Adblock on it and JS out all the comments.

Not if what you show isn't the primary market of YouTube.

YouTube using you.tube would lend credence to the rest of the .tube TLD actually.

This is already a gtld: https://icannwiki.org/.tube

It was registered in 2016 by MarkMonitor. My guess is that YouTube already owns it.

Seeing as ICANN already has tube. , it's unlikely that that would be allowed.

What about .lcd .oled for next gen?
