Apple are the one that made sure that people had to do business with them for anything relating to their platform. After getting my Windows license, I can works on stuff compatible with Windows without ever interacting with them, hell I could do that without even interacting with them at all if I used open source software. I could sue Microsoft and they could decide like you to no longer do any business with me, and it wouldn't affect my capacities in any way to make a Windows compatible software.
