that's not how NDAs work
publicly available information can be talked about.
you may be held to any constraints in the NDA associated with disparaging comments -- but about the actual information -- public is public
To be fair, the agreement is clear that it only applies to 'confidential information' as opposed to reviews or things you create (and as opposed to feedback "provided to Amazon", which they own).
But 'confidential information' is not defined in the agreement, and without expiration, I'd still be nervous. Perhaps I overworry.
