Microsoft didn’t create the entire product from the ground up. They created the software only. Without the software, a whole lot of hardware was obsolete. Apple creates both the hardware and the software. They are 100% at loss if the software pushes consumers away.
Doesn't matter. That is not an excuse to break the law.
There is simply nothing in the law that gives a company immunity from anti trust law, if they built both the hardware and software. Such a law simply does not exist.
