> if I choose GPL today, I have poisoned that code from myself for the rest of my life If you're the copyright holder, the terms of the GPL don't apply to you. It's a license that you give to other people. You can't revoke the license, of course. But as long as you haven't accepted contributions from other people, you can "fork" your own project and take it closed-source. (I agree with your analysis in general. Most people don't understand the restrictions placed by the GPL.)
