I think the purpose of the thread was to say they're removing something that was added, and the majority of REGULAR people don't know about MPC, VLC, or any other player.
And it won't make the OS any cheaper. REGULAR people will just have to spend more to get that functionality.
take this for example. buy a computer with windows 7 and a bluray player, windows 7 doesn't support bluray but the computer will still come with the software needed to play it.
the only people who will have a problem are the ones that make their own computers but if they can do that im sure they know how to install a codec pack.
