Linux's worst enemies? Linux fans
Do you know why Unix failed to take off as a mainstream operating system? It wasn't because it was too hard to use. Mac OS X, the universally acclaimed 'easy' operating system is built on top of BSD Unix. It's certainly not because Windows is better. It wasn't and it isn't. No, I put most of the blame for Unix's failure on its internal wars. Unix International vs. Open Software Foundation; BSD vs. System V, etc., etc. For the most part, Linux has avoided this.... for the most part.
That's not to say that Linux doesn't have its share of internal battles that don't do anyone any good. Free software founder Richard M. Stallman's insistence that Linux should be called GNU/Linux puzzles more people than it does bringing anyone to Linux, or GNU/Linux if you insist. In the last few days though, another Linux family fight has erupted.
This time around, it's open-source developer and anti-patent political lobbyist Florien Mueller accusing IBM of breaking its promises to the FOSS (free and open-source software) community of not using patents against it. Mueller's is ticked off that TurboHercules, an open-source z/OS emulator company, over its possible misuse of IBM patents, which includes two that's covered by IBM's pledge to not sue open-source companies or groups using these patents.
