I don't believe that the majority of people who buy 500€ PCs would spend money on Visual Studio. In the Mac case, nobody pays for the compiler because Clang is open source - this is a massive oversimplification, but whilst the fact that Clang and Make are distributed in the standard OSX base install is a value add in my book, I don't believe that it's something that people pay for. Also, the people who buy Apple hardware are a completely different set of customers to those who buy 500€ PCs. However, this is all a bit moot as you and many others have pointed out that the community edition is out there and it is usable.
