Why Mark Zuckerberg wants to redefine open source so badly
(www.zdnet.com)
This is a most excellent place for technology news and articles.
So as I understand it, under the OSI definition of the word, anything distributed under a copyleft licence would not be open source.
So all software with GNU GPL, for example.
That's incorrect. GPL licenses are open source.
The GPL does not restrict anyone from selling or distributing GPL-licensed software as a component of an aggregate software distribution. For example, all Linux distributions contain GPL-licensed software, as the Linux kernel is GPLv2.
