Here's a probably silly analogy: If we think of Ubuntu as a device being launched into outer space, various components are jettisoned as flight proceeds.
As long as the people who contribute to the development of the components to be jettisoned understand what their role is (or was) there shouldn't be any ill-will.
That's why it's important for a person whose job is to "manage" the community, if the title is to be taken literally, to do a thorough job of explaining even patently obvious matters patiently and politely and honestly (without meaning to imply any deliberate attempts to mislead anyone by anyone).
I fully understand that the role of the "community" will change over time and, as opportunities present themselves, "course adjustments" will be needed.
To my mind, just because something is on ubuntu.com doesn't automatically make it "community-owned".
It would be interesting to see the repercussions if this forum were to suddenly go down permanently.

Ask Ubuntu seems to be a more Canonical-approved site. UF seems to sort of seem like a rock in the path for Canonical.
