Actually there's a strong power law going on with microtransactions. Most players don't spend any money at all on them; some spend a couple bucks on an item or two. The model becomes profitable because of the top 1% of spenders — "whales," in industry parlance — some of whom have deeply unhealthy relationships to the gambling mechanics and social pressures underlying microtransaction economies.

So it's not exactly true that the public are voting with their wallets here. It's a profitable business model, but the majority of people do not engage with it, and consumers as a whole would be better-off if it died out.
