Ok. I invite you to do the math to calculate how much it'd cost to store 10 gigabytes of data on a worldwide CDN.
The amount of money is a non-issue. Rather, it's an issue that is the opposite from what you think - the money which was spent on the m68k and early PowerPC hardware which we typically have represents a much larger investment into the Apple which exists now than a top of the line Mac Pro bought today would make. The pennies (if the cost is even more than one penny) per month spent on keeping those old files is completely meaningless when it comes to the amount of importance that those products have in where Apple is today.
