The curse of overchoice
Overchoice is actually a term for when a consumer is given so many options, often varying in ways which are meaningless or confusing that they end up making no choice at all.
Linux has always had that issue and it is illustrated in the article in all the desktops that exist or existed. I expect most prospective Linux users just want to install the thing and use it for something. They really don't care what desktop is powering their experience providing it is easy to use, discoverable, familiar, doesn't throw any nasty surprises at them and lets them get on and do stuff.
