One of their screenshot examples flags inefficient code in crypto libraries, and the suggested "fix" is "Evaluate switching to the Amazon Corretto Crypto Provider ACCP". I don't know enough about the subject matter area to know whether that's the right move, but it's interesting that CodeGuru is apparently, among other things, an opportunity to pay Amazon to upsell you on replacing some of your code with one of the panoply of services in the AWS universe.
In the future, You should do a quick search before naysaying. This crypto lib is free and offers non-negligible performance gains.
It's still increasing your dependence on AWS systems and software.
(The upsell price may be free for now, but who knows maybe they add a premium version or enterprise features in the future)
I imagine that the tool will be used for recommending more amazon services in the future, and this is possibly a poor POC of more to come.
It's not an AWS system or service at all though...
This is like saying that using React will lead you to be locked into Facebook?
So why is it under AWS[1]?
FYI, as I commented below, it's also available on Github under its own user and with a very permissive (GPLv2) license: https://github.com/corretto/corretto-8
