Simply those employees referenced in the title of this post.
> They were making comments to the press while being Amazon employees something Amazon was in breach of company policy.
Well, and identifying themselves as such. That second part is key. It's not just, "I think XYZ about climate change." It's, "I, bjorne, an Amazon employee, think XYZ about climate change."
> So the policy requires people to not disclose that they work for Amazon while talking in a public forum. That's insane.
Why is that insane? It happens all the time. I don't feel the need to trumpet my employment status when talking about things that are entirely unrelated to my work there.
