How many engineers and executives from 1990-1998 do you suppose are still working full-time at Microsoft today? I'd place my money on it being a single digit percentage.
Pre early 1990s, Microsoft had a modest amount of market power and wasn't infamous for abusive tactics. Post anti-trust years, Microsoft's competitive abuses contracted to negligible levels by necessity.
So out of ~42 years of existence, they abused their temporary monopoly position for about ten of those. And you can't let any of that go, even after two decades. That doesn't seem overly dramatic to you?
Microsoft were terrible in the 1980s too (I have a Gates signed copy of MS DOS encyclopaedia here to give you an idea of how far I go back). They abused enterprise customers all through the 2000's. They screwed people on audits, certs, all sorts. This is a consistent negative all along.
This isn't a 10 year stretch, it's persistent bad behaviour AND it hasn't actually got any better. Enterprises are still getting screwed and they're pretty much steamrolling everything.
You have to be stupid to trust them at this point.
