    i‘m not familiar with the differences. I know they differ in terms of „can the end product be closed source“ but no idea which one does what. I read up every time i need to use one but hasnt been too often.

      GPL is a “copyleft” license aka a “viral” license. It forces anybody who uses it to keep the software open but not just the code, also the way it is being used, and to use the same license if they modify the code, or distribute anything made with the code, and these terms are perpetual and unrevokable.

      Basically anything GPL will keep being GPL and anything that comes into contact with it will have to be GPL or take certain precautions to avoid becoming GPL.
