It's making them very little if any to make backwards compatibility, and uses a lot of their resources for the pittance. Micro$$$$oft for you.
You mean 'Good business sense for you'?
Microsoft, like every other business, wants to make money. And spending major man-hours to make backwards compatibility work for a very minor and small part of the market that they'll never see money from is just good business sense. With such a small percentage of gamers wanting this, and that number just getting smaller, why waste the time and money?
You can't blame them for not wanting to throw money away.
