Do You Believe in Free Beer or Free Speech ?

Nicholas Petreley is uspet about the developers who are violating the spirit of GPL license and creating their own versions of licensing. According to him the spirit of opensource is "share and share alike" and as Free Software Foundation puts it, it is free as in "free speech" and not free as in "free beer". The article further describes how developers have invented some license compromises.

Here's the crux of the matter: It's illegal to create and sell a proprietary application based on GPL code. Given the reality that people are always going to create proprietary applications, developers invented some license compromises that make it possible to build proprietary applications on open-source foundations.
