An objective listing of the numbers would have been fine, but the negativity expressed in Greg's presentation is disturbing. The editor (who usually isn't afraid to inject his own opinion) is being unfair by reporting on the "picking on Canonical" without pointing out that it is plain wrong.
All Ubuntu components are released under an open source license. Patches and bug reports are actively pushed upstream. They should be praised for the contributions they make to the kernel and other projects, and encouraged to contribute more.
Instead of putting down organizations who contribute only a little, please focus your energies on praising those that contribute more. Any contribution should be gracefully accepted.
