What about Linux kernel and Android? There is an argument that companies should prefer the GPL for their own software that they open-source. It goes like this. If you are the copyright holder you own the software anyway and can change licenses at anytime so you are not bound by the GPL. However, your competitors (and future competitors) are. Therefore the GPL protects your company from someone else forking and closing the source for their improvements in the future.
