My comment was more directed at the OP's assertion that poker is not 'productive' because it is zero-sum. I personally don't see how injecting corporate sponsors into otherwise zero sum games (only one team in sporting events can win, only one chess player can win the tournament) elevates competitive pursuits outside of poker to what can be considered 'productive'. OP's view could be that all of these pursuits are equally unproductive and that would be fair enough.
