Motivate them to be mindful of the shoulders they stand on. The bad PR is that this at-a-glance anti-Amazon post is at the top of a popular tech forum.
The OP seems to be disappointed with how they handled it, and an Amazon agent even replied to agree and apologize. Plus, this is not the first time that people have reported similar feelings about Amazon's lack of appreciation for the permissive open source code they use.

I don't know exactly, but I think it starts with making efforts to maintain good relationships with the open source community members who work for free to enable Amazon's (and others) products to exist. Regardless of whether they explicitly demand it up front.
