You've answered what you describe as a "lazy dismissal" with what appears to be one of your own.
The big difference is that most "large companies" people will work at are not Google and Facebook. Name any other enterprise who's motto is "move fast and break things". That is a rare culture. Even Google, who's engineers report that they're catching a bit of the dread corporate-itis is still different from your average enterprise.
More commonly, enterprise is known for being a place where fast moving is discouraged, individuality is stifled, pointless bureaucracy is the order of the day, mediocrity is indirectly rewarded, and productivity and common sense take a back seat to political demands.
