If people using AWS for your organization can't be bothered to take a few minutes to RTFM in its entirety (AWS has excellent documentation, compare to Azure's docs.microsoft.com behemoth of confusion), they shouldn't have access to reconfigure you're entire cloud infrastructure. Buckets are sensible private by default. If you don't know what you're doing, leave them that way.
This is sarcasm right? AWS doc's are okay, but not great. Honestly, their documents are pretty piss poor. They have contradicting statements depending on what tool, they have 100 exceptions for integrating their own toolchain, and the perspective and context is never clear. Sure...their basic stuff is well documented....but it's constantly changing and their system isn't versioned in a way that is easy to upgrade or transition legacy systems.
