I don't know what he meant by trying to force freedom on the world, and I certainly don't know how GPLV3 would accomplish such a task.
Developers have the choice of writing proprietary code, GPL licenced code, BDS licenced code, public domain code etc. I trust code authors are perfectly capable of choosing the licence (or lack thereof) for their code. If you want to use someone else's code, you abide by their conditions, be they monetary, licences, or whatever it is. If you don't like the conditions you leave the code alone, it's simple really.
