"Oh no, a more expensive, higher-margin product that we own will cannibalize a less expensive, lower-margin product that we own." -- nobody ever
This kind of "cannibalization" is a modest tactical concern about the details of your financial forecast. If someone cannibalizes their more expensive, higher-margin products with a less expensive, lower-margin product, strategically and intentionally as part of a big plan, then quote them as a visionary.
I mean, Kodak invented the digital camera, said it was too expensive to ever be viable, and then let it kill them because film was their "high margin" cash cow.... It happens. Short term blinds long term more often than you would think.
That'd be more convincing if they had any really dynamic, powerful product lines within Mac. Given how many Mac skus are in danger of disappearing, it looks a lot more like neglect for a company that makes like 95% of its revenue through iOS and basically keeps Macs alive as a dev tool for iOS.
Isn't that part of the cannibalisation ?
For instance their push for the iPad Pro killed a lot of their own desktop sales I think.
It's often overlooked because the iPad is not squarely a desktop replacement, and compared to the iPhone it's small potatoes. But it still sells a ton more than the Mac.
