AWS ground services are odd, they really don't fit in to Amazon's business model of large scale and cheap to run as the nitty-gritty of operating a radio service has a lot of country by country rules along with the ITU oversight. What they probably hope to achieve is folks using AWS storage and servers once data comes down, but even there you might be better elsewhere.
There are many others offering ground stations as a service: ATLAS Space Operations, RBC Signals, Leaf Space, K-SAT, Swedish Space Corporation, Contec Space, etc, etc.
