- Vorbis was never threatened by MPEG LA, so it is undoubtedly completely patent free.
(MPEG LA never misses a chance to spread patent FUD)
- Windows supports mp3, so it isn’t because they want to push their crappy wma.
- The GPL allows distribution alongside commercial products, and
- Even if they fear to ship GPL software, they can still load it automatically, like they do with XviD
So why can’t a windows customer not simply drop a ogg vorbis file into his/her music library and listen to it via WMP?
PS: To counter misconceptions: They already download the GPL’d XviD codec on demand, so they already have 99% of what it takes to do the same with Vorbis. It would take me about 5 minutes to do this, if I were familiar with the WMP code base and directshow filter system.
PSS: I was told to ask this here rather than on stackoverflow, so i do.
