Two people, one idea. Richard Hillesley from IT PRO also writes about companies who don't give back to the open source community, like Apple.
It makes for an interesting read and I think his article is much better researched than my own I posted here recently. And showing the dangers of some open source licenses he concludes developers should be careful in their choice of open source licenses.
The GPL, he concludes, not only protects from "strip mining" companies, but also (though IMO less well reasoned) from fragmentation and forking of the code.
It seems Hillesley's article is a response to an article by Fleury.
