Couple things. I did not write this as noted above. It is a copy/paste from
the FSF website.
But yes it is encouraging them to use Ogg in place of MP3. Well for the
first two you mentioned Windows and Mac ogg support can be installed
(http://www.vorbis.com/). Secondly many browsers (free and non-free) support
it (Firefox, Chrome, Opera).
Either way you are arguing from a technical point of view. Your argument
stems from the fact that the majority of internet users may not have ogg
support by default. The FSF's argument is that the show This American Life
did a show criticizing software patents. Then they deliver the show in a
patent-encumbered format. Their argument is that this is hypocritical. It
has nothing to do with how many people can support Ogg but it has everything
to do with they are doing what they are criticizing.
