Facebook and Profit

While I agree with mostly everything that Courtney asserts here, my question lies with the last sentence, the comment that Facebook is now about profit. Hasn't it always, to an extent, been about profit, from the first time it took money from an individual or a venture capital firm? Surely these companies were not throwing Zuckerberg money out of the goodness of their hearts but out of the promise of future funds returning to their wallet.
