"In addition, the order requires the defendants to notify Amazon, Inc. that they purchased Amazon reviews of their Quality Encapsulations Garcinia Cambogia capsules and to identify to Amazon the purchased reviews."
Online reviews don't work without trust. Maintaining trust is done by Amazon in this case, but sometimes the job is too big, especially at this scale. Amazon needs better tools perhaps, but the judgement of a court, backed up by a state? Damn, that is a powerful way to ensure there is some minimum level of trust in the marketplace.
I'm against too much government interference in the marketplace, but it's in everyone's interest to increase trust in the marketplace rather than let it become a market for lemons.
