While it may be comforting to think you're just sticking it to "Amazon", if you look at almost anything you're doing, you're going to see other people who are really at the other end of this apathy. Whether it's co-workers you're blocking or giving half-effort to, customers being ignored, or the new engineer that is neglected.
Is there some purely "amoral object like Amazon" stuff that's part of it too? Sure. But at least in my experience, folks who are just phoning it in cause real stress for coworkers and others, and that definitely relates to personal integrity.
Man, all of that sounds awful for those coworkers and customers. But it isn't GPs problem. It isn't their company. He doesn't employ them. He isn't responsible for their experience. Put the blame on their poor experience squarely where it belongs: management. Why is shitty management letting some underperformer ruin things? Super convenient to claim personal integrity and shift the blame to the underperformer when management is clearly not demonstrating personal integrity and protecting their team and customers.
