I can't think of a single season in which they haven't "left money on the table" by denying one group or another that ultimately proved to be successful. Similarly, there hasn't been a single season in which there wasn't at least one failure.
Venture Capital is, at its very best, a gamble, and it's a gamble in which there are a near infinite amount of variables. Product, team, market, vision, future, government regulations, etc.
I don't really know how this would equate them to Google, Microsoft or IBM, especially as except at a very surface level, those companies aren't really all that alike. If the accusation is just that they're slow moving giants incapable of innovating, I'd warn that 1) that accusation isn't fairly applied to the references, and 2) that even if that were the case, isn't really a critique, except where it might be applied in the context of failing to make money.
Seeing the recent batches, it appears that the money-making focus has definitely been more B2B than in earlier batches, but that's likely as a result of B2B proving more profitable over the long run than it is to be attributed to a lack of innovation. As a money-making endeavor, I'd wager that betting for more companies to make less profit than in the hopes of finding one Facebook amongst a bunch of flops is the more humanitarian path of funding as well, but that's another topic altogether.
