Can you give some actual specific examples though? Claiming that "Linux isn't welcome on Macs" suggests that Apple made deliberate decisions to prevent something. A far more likely scenario to me, is that they just don't even consider it at all. Apple makes money selling hardware, and services, and writes/distributes software to facilitate those two things.
