But I <i>would</i> give my bank credentials to Zuckerberg (say we meet at a restaurant in Palo Alto and he asks for it). The asymmetry of the situation means that he will lose much more than the meager amount in my account if he steals the money. So that questions is rather silly.<p>I understand that the question really means "give you credentials to Facebook", where Facebook is proxy to any big company. This is a harder question, but one that I face often in practice, giving out bank account info, SSID number, credit card numbers, etc. The answer, evidently (since I and millions of other people do give this information out) is yes. The above answer still applies, these companies still stand to lose more than me if this information leaks or they mismanage it.<p>In summary, the richer and visible an entity (real or corporate) is the better I feel about providing sensitive information, if it should be provided. This means that teh sort of main message used here ("would you give your account info to") is irrelevant. Being open source is a huge step up, but for the general public either it doesn't mean much or else is a detriment, since the thinking is that, if it's open, "hackers" can also see the code and find ways to exploit it.<p>So how can a small startup ever compete with large established companies, since this creates a chicken and egg problem?
