I thought the A&P story in particular was peculiar, since they presented it as an argument for not regulating Amazon, but looking more carefully into its history (on Wikipedia), I would say what happened to A&P was probably beneficial to consumers long-term. So if FTC looks at how the government handled A&P in the 40s and uses that as a model for dealing with Amazon, I would say it's not necessarily a bad thing.
