Is this really an AWS issue? Sounds like you were just burning CPU cycles, which is not AWS related. WebSockets makes it sound like it was a data transfer or API gateway cost.

I doubt they would have even noticed this outrageous cost if they were running on bare-metal Xeons or Ryzen colo'd servers. You can rent real 44-core Xeon servers for like, $250/month.
So yes, it's an AWS issue.

Where, for instance ?GCP exposes their cpu models, and they have some Haswell and Broadwell lithographies in service.
Thats a 10+ year old part, for those paying attention.
