It probably has to do with the enshittification of Amazon, at least in part. Note how he praises the recommendation algorithm, while in a talk I recently saw he criticized how that same algorithm now pushes promoted products and Amazon knockoffs over what would be best for the customer.
The quote from the TNR review is genuinely insane. Validating my intense dislike of Yasha Levine that they genuinely think a license to use the internet is some sort of reasonable response.
I wish there were better critics.
