The desktop users on my network might have difficulty doing any of those
things, since their "desktop" access is via VNC tunnelled through ssh.

However, now it seems they can arbitrarily install software into /usr,
on a server that is (for some of them) in a foreign country, because of
something called PackageKit.

Can you see why I might not like that situation?

Yes. It's changed the behaviour of my server from trusted to untrusted.

In spam terms, that's what they call "opt-out".

I don't like that much either.

Timely discovery of an unacceptable condition, does not somehow make
that condition any more acceptable.

It didn't fall.
It was pushed.

Yes, maybe complaining about the subversion of 40 years of UNIX security
is being somewhat petty.
