"Old" schoolers have and will likely have for ever that evil 90s vision of MS. However it is changing a bit in that people too. They still may be evil, but at least the look more modern (opensource, new technology, using/contributing to Linux etc).
However the important thing (for MS) here is new people. If you come into the scene now or in a few years you only get to know the "new" masked MS image. Yes, they are still doing dubious stuff but is all under the hoods, buried by layers of hype, cloud, linux and fireworks.
Rebranding some big stablished company with that kind of history is something that takes a long long time.
