The difference is that the GPL is designed with users in mind. The idea being that if you have the right to run code, you should have the right to modify that code. I'm sure you've used software that has frustrated you, knowing full well that you could easily fix the problem, if only you had the source. I expect every programmer has had that thought at least once. That is what the GPL is designed to resolve. The MIT license, on the other hand, grants no rights to the users.
