It's not that society, or even we as HN commenters, have decided that "this is fine" because they weren't as blunt as they could have been, but they're minimizing the overall negative emotions. By having excuses and saying they're still donating $x a year, some percentage of readers who would have started to look for products elsewhere will instead go "sad, but the impact is minimal" and likely won't second-guess using Amazon for purchases.

What if we legitimately object to the truth about their motives and/or behavior? Why would it be on us to coddle zillion-dollar corporations? It's not my job to make it easy for them to be terrible.
