> games built with Unity depend on LGPL code by default (hello glibc!)
So I'm being needlessly pedantic here and this doesn't necessarily go against the OP's point, but since I find this sort of stuff interesting I'd like to point out that glibc is actually GPL not LGPL. There is however an alternate license that applies to programs which link against glibc, with the intention being that the GPL prevents you from distributing glibc as part of a non-Free compiler. I'm not sure of how exactly this is expressed in the legalese but that was my understanding of it.
