This is my experience as well with AWS accounts in the 2-4M/year range, the biggest upsell they always try to make is Enterprise Support, but for the rest they are usually happy to help you cut cost in the short term - as long as you stay with them in the long term.
The incentives are nicer here, from what I’ve heard: AWS TAMs are not reviewed in revenue at all. And cost savings for customers actually counts as a win for them.
