I would probably be considered far to the left of most HN commentators, but I still find moves like this to be pointless.
Ebay, Amazon, etc are all private companies. So I appreciate the point of view that they can operate as they like. But they really shouldn't be prejudiced as to what they sell on their platform, unless there's some form of law-breaking going on (for example the Anarchist's Cookbook).
I'd prefer something at least like how WB handled older Looney Tunes or Disney handled the Muppets - add a disclaimer before relevant episodes explaining objectionable parts. But outright delisting from sale is wrong.
Ultimately these types of moves are bandaids on the real problems we need to solve, like police reform, the schools-to-prison pipeline, the war on drugs, etc.
