Wait, if you don't care people adopt it on the desktop, why do you even care that Ubuntu exists? In what way does its existence harm your Linux experience?
I'm pretty sure GNOME shooting itself in the foot has nothing to do with the introduction of Unity.
Upstart did get adopted by Fedora for a while, but that's just Fedora being Fedora (even now it's replaced with homebrewn systemd). I doubt hardcore Linux users were affected; the distros they use didn't adopt them.
If there's anything you might be annoyed with, maybe it's the Eternal September effect: forums getting filled with noob questions who by people don't RTFM, or the pollution of search results of the keyword "linux" with mostly Ubuntu-centric stuff. But a simple google-fu takes care of that.
