Having worked for AWS, one of the things we got a lot push back from was offering something free and then walk back from it.

AWS really strongly focuses on gaining customer trust, and they will only lower price, and never increase price. They won't turn off things until the last customer stops using it (they might stop new customers from onboarding)

I did not enjoy working for AWS so I left pretty fast, but some of the customer obsession there really impressed me.
