Nah, then it wouldn't be a rumour, it'd be a leak. If you pay enough attention to the Apple ecosystem and horrendous tech journalism that describes it, you come to know the difference — rumours sound like Windows/Android-user wishlists that macOS/iOS become more like what they're used to, leaks sound like … well, like what Apple would do and does.

Sometimes. But there’s never been any rumours about merging iOS and macOS, and Apple has always said the opposite, again and again.
