Really? Evil? I don't buy it one bit. He sold a set of software products that companies wanted to buy. Products that were no fun to support, of course, or for geeks to use in many cases, but let's please not confuse "icky" with "evil".
"Evil" is probably too strong, but Microsoft's misdeeds were considerably worse than merely making products that were less than ideal. Microsoft engaged in some pretty shady business practices which were clearly detrimental to the competitive landscape, harming consumers not just by providing inferior products but by actively preventing better products from being able to reach them.
The most serious of these actions was in the agreements they made OEMs sign in order to sell machines with Windows (and before that, DOS). Because the MS OSes were dominant, OEMs had to have access to their products, so Microsoft leveraged that by requiring OEMs to sign exclusivity agreements guaranteeing that the OEMs would not offer for sale PCs with any competing software. This is the abuse that the anti-trust trial really should have focused on, not the browser wars.
There were many other examples, though. Lots of cases in which Microsoft abused their OS dominance to prevent competitive apps from running well, stabbed business partners in the back, made moves to suppress useful new technologies until they could get around to making their own (generally inferior) version, etc. Largely, this was just business as usual for an aggressive and not particularly moral company, but given Microsoft's commanding position much of it really crossed the line.
And, of course, there's the fact that when Microsoft got hauled into court and ultimately signed a consent decree agreeing to limit certain anti-competitive behaviors, they just ignored the decree.
I could go on, but it doesn't matter. All of that is in the past, because Microsoft, while still very powerful, is no longer in a position to be as dangerous as they were, and the company does seem to have mellowed and become a somewhat better corporate citizen as well.
But they definitely were much worse than what you describe, though clearly not evil on the scale of ISIS.
