I'm currently reading The Infinite Game by Simon Sinek, and he talks about exactly that: is your game finite or infinite? If infinite (like any business), there is no "winning" in that kind of "game" because there are so many standards by which one could say he beats the competition (win): is it market share, cashflow, valuation, innovation?...

Symbian was probably right about how it was handling of security, but it "lost" by disappearing from the game.
