Unlike Sony's Playstation platform, MS-DOS and Windows OS platforms enable PC hardware cloners to have a unified software + boot loader ecosystem which resulted in healthy PC hardware market competition. Your argument is hypocritical.
Read some history, watch some documentaries on computing in the 80's. Look at how Windows came to be!
As to "healthy PC hardware market competition", that was basically down to IBM fucking up and not nailing down the original PC's specifications and hardware vendors cloning Intel's hardware. MS main contribution was to put themselves at the center of the spiderweb and create a near monopoly for themselves in the OS space. This in spite of the fact that their offerings were typically inferior to their competitors.
MS got to be huge by being the dirtiest players in the game. That's a historical fact.
