I think you're reading too much into my argument. I never said you win _forever_ but that it's not worth trying to win market share iteratively when an incumbent with heavy network effects is already well serving your niche. I'd argue myspace is a perfect example of this, largely due to when you look at when it was finally dethroned, it was VERY sudden, and came after years of the platform languishing from a user point of view. It took a hell of a lot of pain to push myspace past the point where the network effect could be overcome.
