No, seriously. Unity (the ubuntu desktop interface) is an abomination. Not a joke. Very serious.
It is painful to even try to use. It forces so many unnatural behaviors, in favor of... I don't even know why. It's not elegant, it's not pretty, it's not fun to use.
It is bad. Horrendously bad. And suited to the tastes of little more than a very small handful of people, who probably open a browser and read email, and do little else, except maybe script shell commands on the rare occasion.
Their decisions arbitrarily imposed on many, who likely still use the distro, simply due to ease of installation (and probably no other reason), and then shoulder the burden of routinely overriding the default install configuration immediately.
