The question is how many actually use them and would pay for tHem? Saying they want something and paying for it are two different things.
They already pay for Office for Mac. It wouldn't cost extra.
A few points:
1. Not all Mac owners would buy Office.
2. Some percentage already have Office so you’re looking at marginal sales Beyond that base. The number is likely much smaller than 10% and not enough to make it worth pursuing.
Beyond the issue of MS Office on a Mac, if Mac users could run any OS natively on the new more powerful Apple silicone, that would draw a lot of Windows users over to Mac, and Apple would sell a lot more machines.
