Them having gigantic margins (e.g. 4x or more on network egress) can mean that any one use case might be better satisfied with something slightly more custom, especially if we stop pretending that administering an AWS account is free and that the overlap between what we need and what AWS offers is perfect. On both sides of this, the thing to do is to critically examine your needs and decide if one or another solution fits. AWS can be a game changer for some companies and an immensely complicated money sink that never gets good enough performance for others.
