> What hosted products has Apple dropped? iCloud might stop supporting old devices but that doesn’t stop you from keeping the data on device or accessing via a new device.

Apple is a bit of a weird case because historically they've been a hardware company first and have done very little in the way of consumer services. But they're just as happy as to kill off consumer products if they want to; they just have a more limited selection to start from (which is itself another layer to the "problem" of trying to use them as a replacement - you can't rely on a product they don't offer).
