I have a friend working at Canonical, and whenever he introduces himself he always includes a brief mention that Canonical makes Ubuntu. I felt it’s very strange (and certainly felt it a little offensive when I first knew him), but came to understand it after a while. It is not common for people to make connection between Canonical and Ubuntu (even IT people!). He needs to establish himself, otherwise many people won’t take him seriously when he talks about Linux stuff. It’s quite unfortunate.
