Isn't that a flawed argument tho?
Apple don't licence iOS or FairPlay - Apple's fault.
Apple don't allow Adobe flash on its devices - Apple's fault.
I suppose it's flawed if your goal is to make Apple look nice to everyone; they quite obviously don't. There's a demographic that dislikes their concepts of end-to-end integration, centralization, and prioritizing unified user experience over customization and perceived openness.
It's quite arguable that Apple would sell more media and devices if they were open to licensing their DRM and including every standard under the sun on their devices. It's also arguable they would lose a certain amount of control over their standards and operating system, however.
If they become monopolies they might have to. Thats what the discussion is about.
Ever heard of generic drugs?
A company becoming an anticompetitive monopoly through abuse of patents/IP won't always be compelled to license existing IP. Generic drugs is a poor comparison, as generic drug makers wait for patents to expire and reverse engineer production methods.
You seem to be pushing two arguments. The first being that Apple is, or potentially will/could become, anticompetitive due to its patents, which I don't really see. And the second being that Apple's integration (Apps, Media, Distribution, etc) makes/will make them anticompetitive. That one is slightly more realistic, although I'd argue that there's no real comparison to existing antitrust cases due to the DMCA exception to OS cracking that was given recently.
