The resistance to GPL isn't just companies, I think you'll find the average programmer prefers using libraries licensed under MIT when given the choice.

It seems like there's a kind of political ideology over what "open source" even means and how it should be practiced.There's a school of thought that says we should switch everything over to viral copyleft licenses. This will "protect" the code and ensure all derivative work is always open source.

Then there's others, like myself, who believe if you want something that's truly "free and open" it should come with as few conditions as possible.
