It's bizarre to me how, despite people criticizing the GPL and GNU as too ideological, the people you refer to - the permissive people - somehow seem even MORE ideological. The GPL to me seems pragmatic - sure technically a minimal license like WTFPL (ignore all its legal issues for now) is some kind of minimalist idea of pure objective freedom. But the GPL has some key "restrictions" that aren't really restrictions and produce an ecosystem that WORKS. Meanwhile the permissive ecosystem is just waiting to be scooped up by bigcos at their whim.
