I think a lot of the disparagement comes mainly from interactions many of us have with a lot of these types of individuals.
A lot of the time the "MBAs" place an overemphasis on the ideas themselves being more important than the ability to execute on them from a technical perspective (although i'd have to say that a lot of developers may have the reverse disposition)
