Apple should have a lawsuit against them.

Gnome didn't copy OSX, they copied webOS. Checkout any webOS tablet videos on youtube and you will find how similar it is. For example: https://www.youtube.com/watch?v=qTOuf1Eb9uA

No needs. GNOME has and always will have a worse UI/UX than Apple.

For what?

For stealing Apple design.

There is so much prior art in GUI design it's very difficult to make a claim like that.

AFAIR only UNetbootin.

Android is crazy bloated, leaved it completely & never look back.
