I think my argument is that open source has in fact won, it just hasn't brought the benefits some people expected it to bring. (And it's totally fine to say, "Having seen the results, I'm no longer a supporter of open source," if you want.) The open-source-is-viable argument was that people will find a business model other than selling the software itself, and the software industry won't collapse when proprietary software becomes unviable - and that's exactly what happened. It turned out the most profitable business model wasn't support contracts or custom development, it was largely software as a service and advertising. It also turned out that this business model was so profitable that there are tons of free-as-in-beer but non-open-source software products out there, including the vast majority of what Facebook, Google, etc. offer.
