Nearly every argument against the GPL is based on convenience or desirability for developers. I think in a lot of ways that's the primary split between the FSF free/OSI open source factions. Reading the GNU manifesto was a lifechanger for me. Even though I've strayed (i.e. am employed producing proprietary software), I still believe the GNU project and the FSF are the most important things to ever happen to the computing world.
