" Let's take two examples everyone knows: OGG/Vorbis. What's the penetration of this open and free format out in the music player industry? Zero"
I know you are just trolling, but just getting the fact straight : ogg/vorbis was read by my samsung 'mp3' player in ~2005/2006. It is also the format of Spotify streams. That's the two examples I've got right now, personnal experience, and it was not a choice of my own at all.
Another example, nearly every single professionnal (AAA etc etc.) video game you buy today uses ogg/vorbis (that's ... free).
You yes, you are indeed trolling. Or dumb. Or both.
