I'm guessing those examples are legion. Always treat your costumers and partners with respect. Another famous example is BeOS thinking they have Apple by the balls to be the basis for OSX. Demanded an outrageous price, Apple just used a BSD.
That is not a good comparison. NeXT was far more than "a BSD". It was a whole bunch of frameworks, development tools, applications, and a hardened team that had already ported to several other architectures. BeOS was still mostly vision at that point.
that seems like it had way more to do with the decision that anything technical. What the team at Next built is quite impressive as well, but the goal was to get Steve Jobs back.
