"However the one thing no one outside Facebook can really know is why they passed on the acquisition."

I know exactly why they passed on the acquisition, and it was not because they thought it would be cheaper to hire someone.

It's strange to watch you keep insisting on this. You said something mistaken when there was no evidence, and now that evidence has emerged contradicting you, instead of changing your theory, you fight to find a way to make the facts conform to it. It's like watching a creationist respond to geology.
