Why? It is great, for me at least! I haven't used a physical disc in a year or two now, especially for movies.
I thought the whole selling point of Windows 8 was to be easier for the average user. Having to buy separate content packs in order to get ordinary stuff to work doesn't seem to help that cause.
I'm a bit on a fence on this. If it is something not-so-widely-used functionality for which MS has to pay license fees elsewhere, I'm probably fine that it is excluded from the base package in order to lower the price. I'm unsure if watching DVD and Blueray movies fall to this, I personally am not going to watch Blueray movies on my new PC, in fact it will not even have a BR drive, but a DVD-RW drive.
But if it is something that MS does itself, or is widely useful and used, or seems like an artificial restriction just to push the sales of more expensive editions of Windows (like restricting the number of incoming connections unless you buy a Server Edition), then I'm not fine with it.
For example, I would have very much preferred that the "Windows XP mode" would have been offered to all Win7 editions, unless there is really some technical reason it can't be provided to Windows 7 Home users. As it is, I presume the restriction is there just to push the sales of more expensive editions. http://www.microsoft.com/windows/virtual-pc/download.aspx http://windows.microsoft.com/en-US/windows/shop/windows-anytime-upgrade
