This is a misunderstanding. Amazon and AWS use "tenets" as a tool for focusing and aligning a team on what it values. The Rust Principles are an application of that tool for the Rust project, not adopting the exact same tenets that teams at Amazon/AWS use. See this 90 second video for a quick rundown of how tenets are used.
Yes, that is exactly what is happening here! When the Rustacean Principles were created, Niko said in his blog post[1] that the idea of creating principles was inspired by AWS. Not that the principles themselves were taken from AWS.
Writing tenets is a tool, like making a checklist is a tool. You can use the idea of making a checklist without using the checklist items.
