I don't think this general notion, that a company can have some kind of intrinsic evil or goodness that is somehow immune to management changes, changes in competitive landscape, and generational shifts resulting from the passage of time, is really rational.
Companies are not people. Companies can't have nor lack a moral compass that tells them right from wrong.
Companies are run by people. These people are the ones making the business decisions and doing the work that enables the company as a whole to do ethical or not-so-unethical things.
The people running these companies can and do get replaced. And when enough of them get replaced, the past actions of a company will no longer be representative of its potential tendencies from that point onwards. This is very simply because a new set of people will be the ones making business decisions and doing the work, and these new people will become the real moral compass behind the company's decision making.
And let's not forget the fact that even people can change. So what's stopping them from changing while running a company, which would thereby be reflected in the actions of the company itself?
All of this change tends to happen slowly and gradually, but change itself, for better or worse, is inevitable as long as a company remains solvent.
Of course, I'm certainly not suggesting that I know for a fact that Microsoft itself has turned an entirely new leaf. In fact, I find all of their recent actions toward limiting user freedom and privacy as disgusting, exploitative and unethical as most others in this thread.
My point is, however, we should try to judge each individual action of a company on their own merit or lack thereof, rather than always viewing them through a lense tinted by some extrapolation of their actions from 20 years ago into some fundamental measurement of the company's intrisic goodness or evil. At the very least, we should try to make an effort to calibrate our lenses to weigh new information more favorably than old, because otherwise, even when the company itself may have long moved on, our opinions of them will forever be stuck in the past.
