This doesn't seem to be as easily defined as you say. The new AWS group is more or less targeted at "avoid bad press" rather than "indefensible politics", whatever that is. Twitter mobs seem to be quite fickle to me and can just as easily eat their own as their usual fare. News outlets aren't a lot better, often following big enough gripe fests and piling on like the rest.

It's not just based on particular politics. It can be any behavioral screw-up done by you or any employee, at any point in your life, real or perceived, that crosses the current cultural expectations. The surface area of risk is ridiculously huge.

It gives activists another angle of attack on your business. If they can create enough of a scandal, Amazon might drop you to avoid bad press.

I don't use any cloud service that isn't available at other vendors. This isn't my primary reason, but it is on the radar.
