Companies undermining consumer reviews undermines the justification for consumer capitalism. The idea is supposed to be that a merchant sells a product that solves some problem real or imagined at a given quality level. The consumer is supposed to be able to make a fair evaluation of the quality and fitness of the product and compare it with their budget and the item's price and make a decision.

If companies systematically and intentionally destroy the consumer's ability to do this, then why should their state charters even be valid?
