Re: Is this innovation, or just diversity?
I do indeed think that commercial vendors have not managed to create a proper webserver, a proper version control system, a proper web browser with fast JS and good sandbox, a nice GUI toolkit during the last 10 years on their own. All the "good" stuff has been full or partial open source. Yes, Chrome is innovation - try IE 8 if you don't believe me. Check the list of exploitable bugs in Chrome and FF if you don't believe me. SVN and CVS are much, much better than all the commercialware contraptions, because they simply work instead of presenting stupid metaphors and half-broken tools. That's innovative.
Ubuntu is innovative because patching is a single-click affair. Linux invented this, everybody else followed.
Apache plugins are innovative and it's stability and robustness is innovative. Just check IIS.
Gcc is innovative because it generates for everybody's and their dog's instruction set.
HTML is innovative because it is not a property of Adobe, Microsoft or Quark.
