I've never worked at a startup that required use of a specific platform unless it was tied to development (.NET, of course, requires Windows, Rails strongly encourages Macs, Cocoa requires Macs). And yes, I would be very suspicious of someone who wanted to do .NET development on a Mac or Cocoa development on Windows. I'm sure both are technically possible, but rather poor choices. Outside of that, Microsoft is pretty expensive, so I can see not wanting to pay for it.
