I had the exact opposite reaction after leaving Amazon. Brazil is a slow, bloated pile of crap that regularly blocked fixes, made it impossible to develop in a non-standard language, and regularly resulted in 100+ dev build blockages due to versioning issues.

Our team was abandoning Apollo for MAWS, so our deployments were bridged between the two, resulting in another twisted pile of incomprehensible script-glue.

Pipelines was ok (!)

Everything on public EC2 for managing deployments (CodeDeploy and CloudFormation in particular) were so broken and bug-ridden and non-performant that we couldn't reliably deploy production code with them.

I prefer open source solutions in almost every way. I actually can't think of a single problem that the Amazon internal stack solves that isn't better solved in the open-source world. Which isn't surprising, given the constraints involved.
