To be fair, I could absolutely understand their decision. After watching the people behind Gnome3 and Wayland pretty much run amok with their ideas and their attitude towards other, dependent projects, I can't blame Canonical for not having that much faith in a possibly unstable foundation. Especially with their plans back then of building a mobile product on it. So I really can't see how Canonical are the bad guys here. It was not so much about more control but against losing it somewhere down the road.
