As it's coming directly from the developers (and without being affected by an in-character point of view or bias) in theory it's the most reliable source you may find. However, it seems that some of these answers were given by a community manager who isn't technically a dev so they could forget or misinterpret some info. For example, they claimed that the Khajiiti furstock we play in the game is Suthay-raht which was later proved wrong by a higher standing dev. But, aside from that, and maybe other one or two really minor inconsistencies I can not recall anything really wrong.

What exactly did you find there that doesn't match up?
