Hmm, weren't the numbers very much disputable? Omitted one of the most obvious numbers, ie. the number of employees in companies, Canonical's 150 (a lot less before) vs. other's thousands. Blaming a small company for their big success is a bit funny. The grandmas and grandpas using Ubuntu cannot be turned into kernel patches.
I find your post a bit trollish, since whatever all the aspects that have been discussed to death, the issue is very disputable and Greg's ramblings very biased-sounding against his employer's competitor. It's about 50% that Canonical has some problems that could be fixed with time and (hopefully) company growth and 50% that Greg has a bit of a problem with rudeness that should not be tolerated in communities since it creates bad spirit.
Regarding the topic, I find it a welcome start to a more fluent upstream handling. I think previously effort and thinking has gone to interacting with Debian, but it's also useful to try to contribute more directly to upstreams.
