  debian-stable
  debian-buster
  debian-slim

Those names are clearly not packages but distros.

  python:3.10-debian
  python:3.10-alpine

Those names are clearly packages based on a distrop

So why not:

  glibc-alpine

This would avoid confusion.

> they make it clear that it is based off Alpine with the glibc package installed

Well, seeing the number of issues opened on the official Alpine bug tracker regarding this package, it seems it's not that clear.

> if Alpine starts going after people for using alpine in the container image name or tag then I now know what distro to avoid entirely.

Alpine starts going after people for misusing the name and impacting their reputation. This is completely normal and understandable.

Marketing and communication is an important part of every projects, even open source projects, this is not exclusive to businesses. If you want people to support your project, you need to protect your image.
