The entire Linux eco-system exists of competing things. Nginx vs Apache, sendmail vs qmail vs postfix, ... the list goes on. There is no singular 'desktop' when it comes to Linux, and there will never be one. Thinking and hoping there will be is simply not understanding what drives the whole Linux world: options and competition.

Can't find a cached version of the actual ubuntu article though.

No mention of mir though?
I checked the date of the post really carefully as well. That is certainly a change of direction.
Seems like good news to me, having a significant player like canonical contributing to the community instead of fragmenting without much benefit can't be bad can it?
I don't use it on the desktop anyway, but I hope that moves in this direction are rewarded by the community.
If they're ditching mobile, there's literally no real benefit to Mir.
