I encourage you to consider how your statement, "I don't trust Microsoft," sounds to a higher level exec or department head. I don't mean this as a criticism -- I notice there's a tendency for ICs to state their opinions in such a way that hurts their perception.
Namely, if you were to state to a higher level manager that you "don't trust Microsoft", you will come across as a crank. Or a developer who doesn't see the bigger picture.
To improve perception, folks should try to reframe their personal preferences ("I don't trust MS") as risks to the business - "I worry that MS will lock us in to their platform and jack up prices". The former is reputation-harming; the latter is being a savvy 2nd order thinker, who looks beyond just what the MS salesman says.
