Some game developers have been able to contribute software using LGPL to get around the restrictions of both corporate legal departments and the confidentiality agreements you have to make with Sony, Microsoft and so on. Electronic Arts for example made a port of Webkit which can run Playstation and Xbox, which is a linkable library and includes no reference to third party API's. Personally I choose a license relevant for the kind of software and what it will be used for. When that includes software I want people to be able to use in commercial software I use MIT. I'm still releasing hard work for free, I don't have your admiration, but people get to use it. Facebook uses the PHP license for HHVM which is a very significant OSS contribution, and has very similar terms to MIT.
