Apart from the standardization and regimentation of corporate events, which I know little about, there is the problem of "too many cooks". For a moment, think of gaming as creative writing. A typical gaming group is like a group of writers, traditionally with the DM/GM/blah blah as head writer. (Some indie games, like Primetime Adventures, make this literally true.) Now imagine a bunch of writing groups collaborating on a larger work of fiction; to maintain consistency you need either a Head of Heads or a Writer's Bible (written by some guy) or both. Even with some sort of gatekeeper, inconsistencies creep in over time and among parallel titles, as comic books, long-running TV series, and movie franchises demonstrate.

Barker, Ed Greenwood, or Greg Stafford providing "official" answers. White Wolf's metaplot delighted some and annoyed others; after publishing the apocalypse of the Old World of Darkness in favor of a new and less cut-and-dried version, fans and dipping sales forced White Wolf to support the old stuff again. The more a game company tightens its grip, the more alternate continuities and die-hard grognards slip through their fingers. So while one can feel a spiritual connection to other fans of Tekumel, Glorantha, or a World of Darkness, each GM will still have his own house rules and carefully inspect crossover characters for conformance to their own variant.
From what I can tell, the Camarilla is the opposite of the RPGA: largely anarchic and bottom up, independent of corporate interference (after some bitter legal fights). From what I've heard it does have other problems, notably cliquishness and (appropriately enough) a feudal hierarchy built into its all important experience system. It's also a LARP, and once you convince people to pretend they're vampires who can become invisible, maybe it's easier to convince them of anything.
"On two occasions I have been asked [by members of Parliament], 'Pray, Mr. Babbage, if you put into the machine wrong figures, will the right answers come out?' I am not able rightly to apprehend the kind of confusion of ideas that could provoke such a question."
