I'm reluctant to say it's cynical because it's not necessarily negative or pessimistic so much as matter of fact. The Op isn't taking shots at Amazon by exposing their motivations.

A higher Minimum Wage is coming and possibly be a priority for Liberals and Progressives after the November Election. Amazon has been receiving a lot of negative press recently for labor conditions and wages. Regardless of the benefits to others, there is a direct benefit to Amazon.

Now if you want cynical... I think it's borderline delusional to think that a publicly traded multi-national corporation would do anything that isn't in it's business interest.
