That's it, for Apple the mere mention is already too much.
Why would anyone want compatibility if they also just could buy an Apple product?
Also the reason why ipads and Vision don't support multiple users: not only should you buy an Apple product, but so do your partner, parents, kids, etc.
iPads actually do support multiple users. They just hide the ability to turn it on behind complex IT management tools that your average user would never be able to figure out.
