I agree, MS is not fly by night. As a computer engineer, I will say that in my professional and personal opinion, they are a hack job. :P Bad example.

I think you just badly worded your note of caution. I have the same pause you do, when I know I'm dealing with a company that has questionable practices, products or track record. But when you've got a company you've got faith in, trust them, stop worrying. You'll have your hair longer.
