'Last month, it finally happened. Six years after its tumultuous switch from GNOME 2 to the homegrown Unity desktop, Canonical announced it was abandoning work on Unity. Going forward, the company will switch the default Ubuntu desktop back to GNOME beginning with next year's 18.04 LTS release. This means Canonical is also abandoning the development of the Mir display server and its unified interface of Ubuntu for phones and tablets. The company's vision of "convergence," as Canonical founder Mark Shuttleworth termed it, has officially died.'
