If his point about ms-dos is in error, then much of the rest of the article is pretty much off the rails, no?
And people were ready to stop doing "Reveal Codes" in WordPerfect 5.1, so Word started driving a lot of Windows adoption.
And like the article alludes to, OS/2 ran like a slug, even after I upgraded to an astounding 4MB of RAM. In my case I was a bit of a diehard though and usually ran Windows 3.11 inside Desqview, with a double tap on the Alt key I could jump between running copies of Windows, as well as DOS and whatever else I can't remember, maybe OS/2 Warp as well.
Microsoft was most certainly NOT a monopoly. They beat OS/2 fair and square.
Monopoly: A situation in which a single company owns all or nearly all of the market for a given type of product or service.
There is nothing implicit in the phrase "Monopoly" that suggests you didn't beat other people based on price, performance, features, customer service, etc...
Microsoft has had a monopoly on the OS and Office Productivity suites for quite a while, with the OS leading the Office Applications by a few years.
Of course, the pretty much ubiquitous presence of MacBooks around me, at coffee shops, and in the offices suggests that they may finally be starting to see some competition in the OS marketplace. And, if the kids these days are any indication, this trend has a pattern:

I think Blodgett's article was reasonable, and certainly wouldn't refer to him as a Dope.
And when you say "Finally see some competition" you're just demonstrating exactly what the article is talking about, discussion that sounds knowledgeable of the history, but isn't.
I worked at a company that produced an editor for os/2 for the publishing industry, and it was pretty slow as you say.
However, I know at least one exception to the reveal codes urgency. My Mother, who is 79, would still be using reveal codes if there was a way to do it on her current xp laptop. She never cared for the windows version at all.
