Somebody wants to use it? :D I thought about something like where people can use it but have to make changed public. I am just curious, what should be changed. But I dont think there is actually a real world use case.

Sounds like you prefer copyleft licenses. I suggest MPL-2.0 or some variety of (L)GPL as they are the most well-known ones.
