There's an argument to be made the other way around:
Maybe if you choose to use multiple platforms you should just deal with the multiple approaches to UI? Why should the single platform citizens suffer from a UI that's inconsistent with the rest of the platform?

Imagine Slack decided that the shortcut to copy text will be Ctrl+C on all platforms. And Windows users who occasionaly use a mac would rejoice because it would save them from having to think which button to press.
