I agree to the extend, that it sounds like Microsoft is in any way special here. Actually, for some time it's opening up pretty much. Apple is even worse, Google will certainly not support MS products in any way if they don't benefit massively.
It's important to understand that all companies are big machine-like systems that have only one purpose: Make as much money as possible. Microsoft have been (and Apple is still ... or is the Apple watch usable with Android?) trying to lock vendors in. Totally OK. Those tech companies are no better than Kellog's who is selling sweets to our kids as cereal. As we all love tech so much, we tend to forget :-)
