There are multiple problems here. First, there's the unsupported claim that the AGPL is somehow incompatible with being production-ready, which seems obviously false. But more seriously, there's the proposition that
GitHub should crack down on this project, which I find to be absolutely bizarre.
The person who opened that issue also made some other claims, like that a more permissive license would allow the project to reach a broader audience. That's undoubtedly true, but I'm going to go out on a limb and say that the author of the project is probably well aware of that and chose an appropriate license based on their own goals.
