Pandora Launches Apple Watch App With Offline Playback Capabilities

No one here can say if Apple is safe from a monopoly case as these are brought by the DOJ. Your point that proprietary hardware is a safety net is wrong as I showed with AT&T breakup due to their proprietary hardware. Microsoft was sued for monopoly practices over Internet Explorer even though users could "easily install" other browsers or use alternative operating systems and they lost as well.

Why is it so hard to understand that, for antitrust suits, market dominance is a relevant criterion to be established?

Microsoft was sued because they had a pre-existing operating system market dominance and leveraged that in order to skew IE market share. Netscape, Opera and other browser vendors were at an unfair disadvantage: Microsoft could give away IE for free and make it up in Windows OEM sales; Netscape didn't have an equivalent channel.

If 90% of all smartwatches sold were Apple Watches (they aren't), and Apple bundled Apple Music (they do), we'd have a similar scenario. But the first isn't true, so the second isn't relevant.

Bundling isn't illegal. Monopolies aren't illegal. Having a monopoly, then bundling a different product in order to try and establish a second monopoly, is illegal.
