Apple did take Wine (well, CrossOver, but that’s wine-based), adapted it for Macs, didn’t create a merge request for a single line of code, and ended up only advertising the new tool as a demo for how well games run on their hardware to incentivize ports, with no intent of using it as a compatibility layer for players.
I bet Nintendo has a lot of patent violations to choose from. They have a patent on such bangers as, rephrased from legal speech to human speech: “An air mount automatically turning into a ground mount upon landing” Source
According to Nintendo, if I understand this correctly, they have the sole legal right to make a bird mount that can also sprint on the ground if needed, because that sure was a special idea.
