The point of different licenses is the thing you ought to be looking at.

The point of mit is to get the licensed thing used as widely as possible. It breaks down any barriers to use. A good example of something that should be mit licensed is an encryption algorithm. A good example of something that shouldn’t be mit licensed is anything else.

The point of bsd3-clause is to prevent the licensed likeness from being used to imply the creator shares some view or idea. A good example of something that should be bsd3-clause licensed is the royalty free music on youtube. A good example of something that shouldn’t be bsd3-clause licensed is a creative work the author wants to have their name known for.

The point of the various gpl licenses is to create a digital commons that all people can access. A good example of something that ought to be gpl licensed is a game engine you want people to be able to freely use and modify but never make secret changes to sell. A good example of something that shouldn’t be gpl is a game engine you want to eventually sell the code of or make secret changes and sell the code of those.

If my language sounds biased, it is because I have a bias.
