I read it as tribalism. Internet commentator with investments in Amazon (either via stock or just by choosing to use their products) decides to spend their time unquestioningly promoting a trillion dollar company for free. It's a tale as old as time, unfortunately HN is far from immune to it. I dislike Amazon and Tesla pretty equally, but then Bezos didn't royally screw up Twitter, so there's that.
