GPL-like licenses are still 'open' by OSI standards as well. So yeah, the permissive-license v. copyleft argument isn't the same one as the Free v. Open argument, though perhaps there's some correlation between what views people have on each one.

Wouldn't you hate it if you did something, like giving money to a poor fellow, and then people are using your good deed to market their ideology (like communism perhaps); even though you think it's wrong?

Now imagine how some open-source authors feel.
