You're beating a dead horse. You say that bundling, in itself, reduces consumer choice. For example, I work for Enhanced Software Technologies Inc., the makers of BRU, the leading backup solution for Linux. Yet McMillan licenses our product to sell as part of their Linux package. Corel licenses our product to sell as part of their Linux package.
Caldera licenses our product to sell as part of their Linux package.
Probably other people do, too. When I was working for LHS, we sold a copy of BRU with every tape drive we sold. Thus, despite the fact that IE was free, this did not in itself result in consumer harm. Any critique of Microsoft needs to focus upon their business practices, not their product line. As long as Microsoft is allowed to leverage their monopoly position in order to prohibit OEM's from meeting customer's needs, and as long as Microsoft is allowed to leverage their monopoly position to set prices that are higher than what a free market would set, consumer harm is resulting.
