I have no objection to proprietary software, because that is how people make a living. That proprietary software license is what allowed the author to quit his job and bring it into existence. The alternative to making software proprietary is not making it GPLed. The alternative is not making it at all! A hobby is not a substitute for a job. I would never characterize copyleft software as "bad:" the author has donated time and energy, and I am grateful. But it is less useful than it could have been. If you're going to write some software and give it away, man, just give it away!
