On top of which Microsoft suit specifically calls out "Intel compatible PC operating systems"

They are talking about Companies like Dell, Gateway, Compaq, HP, who made intel hardware. What choices did those companies have for an OS for their computers? Windows effectively had a 100% monopoly. They aren't talking about consumer alternatives, where you could by a Mac.

55% isn't a monopoly, Android is a very good substitute, so not really comparable to the 90s where you needed a desktop and Office to get work done and Windows controlled 90-95% of the market.
