I think a big part of this is the misattribution of the .org label combined with overly simple design. People believe that craigslist is altruistic and trustworthy because it has given the appearance that it can only just keep the lights on and pay the bills. A real company could afford a logo designer! So they've gotten huge (not in number of employees), but they're behaving just as arrogantly.
