Similar career arc to me but I actually recognize that a company is not a person, it is a collection of people that change. The Microsoft that exists today is far better than that of a decade or two decades ago.
Don't let prior experience prevent you from seeing when great stuff is happening.
This kind of argument appears often in threads about companies not being one entity - but it is wrong. An engineer asked by management to implement enthical program parts can either play along (thereby endorsing behavior) or go home.
A member of the legal team cannot decide to NOT extort e.g. Patent fees from e.g. Android handset makers, or allow e.g. BeOS to be installed by licensed vendors that were forbidden to do so.
A company behaves like an individual, sometimes schizophrenic, often psychopathic or sociopathic. But policy, and reponsibility is not, in fact, up to individual employees.
What you say is true of a group of sports fans, not of a company. And having watched Microsoft's stacking of the ISO committees, patent extortion and chilling effects, SCO proxy war, scathing disregard for industry standards etc - I'll say that I think they have earned all the hate they get here, and then some. The fact they they are not doing as much damage these days is mostly thanks to sliding away from the dominant position - but the culture is still one of bullying.
