Open Source hasn't really taken over the world, if you look at end-solutions. As a software developer I might use an open source database, but as end-user I'm probably not going to use open-source accounting package - but I will use an accounting SaaS system that happens to be implemented with that OSS DB. As a software developer I might use an OSS operating system, but as end-user I use a software that has been packaged and maintained by corporation like OSX, or even if OSS in license, has been fully packaged like Android.
