Because microsoft got to big, which distorts the market. We learned this in economy 101 on high school: a monopoly is bad for the consumer. This here is technically not a monopoly but it is close. The producer of good A is using its momentum in market A to push a product in market B. This way, any big conglomeration can use its big fat ass to push innovation out of market B. All it has to do is offer product B for free, with a purchase of A. This promotes lazy consumerism, nothing good ever comes from it. This is why coupled sales should be banned. This is why the EU tried to uncouple browsers from OSs, why you now have to explicitly choose a browser.
