But the direction of Linux as a GPL project is largely controlled by corporations e.g. Redhat now a.k.a. IBM, Intel, etc. GPL is not a cure all, it is a tool. Some licenses are better for some purposes. Use the right tool for the right job. It is nice that we have compilers (and OSes) under both licenses, it shows both strengths and weaknesses of each type of license. There are strengths, and weaknesses, to both models, and to other models, such as Intel's optimizing compiler.
