Actually, I have seen small companies do just as badly at things, but they don't stick around for long, because they die from these mistakes. The ones that CAN make mistakes like this again and again, must be huge, and also their mistakes are more visible because they're big.

Plus, small companies that make big mistakes that do survive, are scarred by the experience and tend not to repeat that particular kind of mistake again. Companies that can make a blunder of the sort described in this story, repeatedly, have to have been big in order to survive long enough to repeat it.
