If you look at the post they're just talking about price discrimination tactics employed by big data companies. Crypto-currencies have nothing to do with this and no role to play. Deal and comparison sites are the solution here basically, and they're readily employed by people who actually use the market and don't just blindly buy from 1 seller. tldr: If you want a good deal, go looking for one, if you don't, you get screwed.
