Quote:You could make the exact same argument against Mir by replacing all instances of "wayland" with "mir". It's just as likely that someone in Canonical will break Ubuntu phones by introducing a bug in Mir as it is for someone in Redhat introducing a bug in Wayland. In fact it's probably more likely to happen with Mir because there's a single point of failure (Canonical) where as Wayland updates done outside of Canonical should be vetted by their package maintainers before merged downstream. So updates get vetted by Waylands project maintainers and Canonical's package maintainers.
However I should point out that nobody cares if Canonical runs Mir on their mobiles, it's the desktop market we're concerned about. We're already used to the concept of Linux not being 'Linux' on our smartphones and tablets - but that's fine because desktop applications don't factor well on a touch screen the size of my hand. I don't just expect my mobile apps to be developed separately, I demand it for basic usability reasons.
I've lost count of the number of disgruntled Windows users (particularly with Win8) who have said I'd drop Windows in a heart beat if Linux only supported the games they play. So I happen to think Valve is the best thing to happen to Linux in a long time.
