Making money is the only significant metric. They may have a large market share but if they're not making money from it who cares?
Having a dozen companies each making a little money represents a much healthier market than one giga-corp taking the lions-share. What we're seeing in China is the market moving to a healthier, more natural and sustainable state.
I find that much more important. As a consumer/customer that benefits me.
Whose interest do you have in mind?
