He's not wrong, you're just misunderstanding him. He's not saying there aren't "valuable" or "interesting" Facebook accounts. He's saying that there aren't enough Facebook accounts with immediate drop-in value to an existing and lucrative criminal enterprise to create a competitive market for Facebook bugs.
I would agree, being that I cannot immediately detail how these Facebook accounts might be useful, but any information is useful, especially credentials.
(Valuable != "immediate drop-in value")? So, he's saying the accounts aren't valuable, but they have value? The subtlety is lost on me...
The info might be useful to someone, but not to the people who are buying vulnerabilities on the black market.
Imagine going to a tech trade show and setting up a stand for your lumber business. What you're selling has value and is useful, just not to the people you're trying to sell it to.
Let's assume the position of a spammer or ~0-day blackhatter... access to the accounts of the most popular website in the world are not of interest? (You could post a URL and have millions of people click it because they trust the poster.)
Is that a retort or simply an unrelated observation?
Edit: My intent was to understand your perspective (and argue...), but this comment goes over my head, and it seems as though it was a thinly veiled insult.
What I'm understanding here is, that while it might be profitable to someone to have an exploit on hand that they can use, the actual work that goes into turning a profit from the exploit may be me costly enough that its not worth pursuing.
Not sure if you read Cryptonomicon, but there's a part there where Randy Waterhouse finds a crap load of gold in the middle of a jungle and then rationalizes that there's no easy way to get it out of there, making it worthless at that moment. That gold has value, but no liquidity.
This is a forum focused on the startup community. The difference between the merely-useful and the truly-marketable has been discussed ad nauseum on these pages, as that difference makes and breaks many startups.
