Right, but that protection isn't unique to microsoft. It also applies to apple and other companies. This isn't an offensive argument in any way, precisely because everybody could've had this.
Excellent goal post shift! Seven points!
The entire argument is structured around corporations/monopolies ONLY existing if government subsidies them. So to win this argument, I only need one example to prove that a monopoly/corporation came into existence without a subsidy.
You've only showed that government subsidizes
all content industries equally (though, those with more political clout get better treatment). You have not shown that Microsoft would have existed in any meaningful way if there were no subsidization at all. Would you like to try again?
