The FDA didn't pressure Amazon. The FDA issued a general warning letter a year or two ago, not to any company specifically, saying that NAC couldn't be marketed as a dietary supplement. Amazon decided to stop selling it. Most other retailers continued to sell it.After pressure from the FDA, so it seems.
Recently the FDA has backed off a bit and stated that they will likely allow NAC as a supplement. See below. FDA formally announces NAC enforcement discretion, but legal hangover remains
