I am the author of a Python wrapper around the App Store Connect API: https://github.com/Ponytech/appstoreconnectapi published on PyPI at https://pypi.org/project/appstoreconnect/ I started the project in November 2018 and licensed it under the MIT license.
I have just stumbled upon a project that is clearly based on an old version of my work (same README and same code with small tweaks) but it's not a Github fork and it has removed the license file and credits: https://github.com/WHDevLab/appstoreconnectapi published on PyPI at https://pypi.org/project/appstoreconnectapi/
How would you deal with this? All I ask is to be credited for my work.
