We can be hard to absorb, that's for sure. I've successfully helped a lot of start-ups, but I (and they) have been careful to ensure that the time I spend there is limited. eBay hired too many MBAs/consultants and stuffed themselves as a result. But arguing that McKinsey alumni are all-bad is clearly over the top. They can produce results incredibly quickly and are comfortable dealing with very senior levels at corporates. Business development and major deals are a specialty. Try calling one when it's time to think about major decisions, pricing, figuring out how industries work and just general business advice.
