I never trusted them and I'm not using their products unless I really must (a customer's Windows server, their Android PDF reader or Google's one, maybe that's it.) But yes, when one is young and exposed to Microsoft for the first time and see them behave it's easy to dismiss the tales of old bad behavior. If one is 40 or 50, it takes a lot of naivety to trust them or any similar corporation. If anybody did, they are hopefully changing their mind because of the facts of the last few years.
