Newsflash: everybody's do. That doesn't automatically excuse them from doing stupid things in the name of those values. This is why again and again I keep pointing to the fact that I am criticizing their actions and not their values. You keep assuming that the values that Mozilla espouses can lead to one and only one possible course of action and that that is automatically the right one. I am saying that this is not so, and I'm pointing to the fact that users are being harmed and no good is coming of it as a sign that it wasn't the right choice.

how would you qualify apple by not supporting theora in safari?

The difference is that with Safari you can install Theora on your system (http://www.xiph.org/quicktime/) and it works just fine in <video> and everywhere else (and yes, it works on Wikipedia.) Apple simply doesn't ship Theora which is a much more benign way of "not supporting" something than disabling it altogether. Mozilla, on the other hand, has specifically chosen to prevent users from using anything other than Theora in conjunction with <video>, and not because it's not possible to do it any other way.
