I have no doubt that you believe you're arguing objectively and in good faith, on important questions regarding Canonical.
However, it's completely missing the point: You are a prominent member of the Fedora community (possibly even an officer of it of some sort, I don't know). It reflects very badly on you - and anybody you represent, by extension - when you wage a bad-mouthing campaign against rivals on forums. However well-founded your bad-mouthing might be doesn't matter.
Your socio-political standing means it is NOT YOUR PLACE to launch such direct criticisms. Rather make them indirectly by promoting those *positive* aspects of your distro which contrast with what you feel is lacking in others. E.g. "More developers get paid to work on Fedora", or whatever your point is. Leave any direct criticism to 3rd parties (e.g. LWN editors) who have at least semblence of impartiality.
Please, please stop..
1. On the flip-side: if it's not well-founded, it reflects even more poorly on you. Though I suspect many people now ignore any of your comments containing the words "Canonical" or "Ubuntu"..
