The FTC is suing amazon for hounding non-prime to join prine multiple times during a purchase checkout to the poing of making the final click to buy likely to also join prime. In addition, the FTC says the number of clicks required to cancel prime excessive enough to be part of the suit.
I've been extremely annoyed by this for years, but assumed it didn't cross any legality boundaries. I am happy that the FTC does not agree with me on that point.
Amazon is denying any wrongdoing, but is allegedly taking steps to dial back a bit.
