I don't think your definition of inequality, which basically equals popularity, is a useful one. The article is about income inequality. While it is true that people always making the unpopular choice would reduce winner-takes-all effects, it's not worth it: it requires great personal sacrifice, and as an individual there is almost no gain: society is hardly going to benefit when you intentionally hamstring yourself by running TempleOS, or when you choose to eat at a bad restaurant instead of a good one.
Surely creating laws that try to limit income inequality makes much more sense, especially when looking at cost/benefit?
