Whether or not Canonical has been able to do it sustainably is still open for debate. I look forward to Shuttleworth being able to announce that Canonical is breaking in their service business around LTS.
I would like to point out that you are attempting to generate Fear, Uncertainty, and Doubt surrounding Ubuntu. This is not the first time you have done that; It seems an ongoing campaign. That is, in my opinion, beneath the dignity of the Fedora and Red Hat communities, and I recommend that you cease, lest it be thought that the Fedora community condones such shady tactics.
