"Again, these accusations appear less than solidly founded. It surely can not be good to start creating an atmosphere where people are afraid to talk to other developers of a project about a bug just because they work for a different vendor."
If you're looking at this and merely seeing evidence at attempts to collaborate, well that's hardly fun and interesting. Try harder to blur the facts around to support some sinister conspiracy theory. That is a LOT more interesting, and sells a lot more ads. This whole talk about thinking from solid foundations is plain silly; everyone knows better than to do that.
But whatever you do, DON'T just go talk to the developer directly to get the actual facts. That makes it a *lot* harder to maintain all the lovingly crafted anti-Canonical memes we've got. Next you'll be saying Kees contributes to upstream or some other madness like that.
