However, I don't know many people who play CD's in the car. I know a couple of people with 10 CD multichangers, but they are the kind of people who generally only listen to 10 CD's anyway. Everyone else either listens to the radio, or has their entire CD collection on an iPod or similar.
When multinationals like Ford start making decisions like this, they do their research. They generally offer an upgraded stereo option for people who are prepared to pay a little extra for better quality. But they wouldn't consider a decision like this unless they were confident that it wouldn't hit their sales. Which means that the vast majority of people are satisfied with sub CD quality audio. And that's the threat to the CD format.
As for debates, even heated ones, there's nothing in the rules to prevent that. And we moderators get involved as much as anyone else because first and foremost, we are members here because we are passionate about music and music technology. But the rules are there for a reason, and more to the point, you have agreed to abide by them when joining. They don't prevent debate, they just require that it isn't conducted in an offensive or abusive manner. And that improves debate.
