My understanding of Microsoft's success was it came from marketplace maneuvers, many ranging from unethical to illegal, not from quality or innovative hacking. Compare Windows with any contemporaneous MacOS, for example. They took over the office productivity software market by illegally leveraging their Windows monopoly. Their initial and core success - getting DOS on IBM PCs, which led to the Windows monopoly - was simply leaping at a business opportunity, I think even before they began developing the product.
Didn't they generate fake errors for Windows running on DR-DOS, or something like that, even though it ran fine? Do you mind that they tried to destroy and monopolize the open web (thank you Mozilla!)?
Well the article is obviously a biased source, but surely developing a) an ALTAIR emulator for PDP-10s (Allen) and b) a pretty much full-fledged BASIC interpreter that was exclusively tested on top of said emulator (Gates) in two months, in the 70s was not the kind of stuff an average coder would have done.
