My thoughts while I was reading through this article:

• The Time and WSJ apps are first-generation.  They both have a long road ahead of them, and the competition is going to force them to get better and provide even more value to their readers.  And they view their competition as any outfit who can generate content, not just the other media companies (they paid attention to the lesson of Amazon coming from nowhere and know it can happen here quite easily).
• Yes, people do need to be able to share stuff (text/links/etc.). Again, I see these apps in the “Make it work” category (the next being “Make it good”, then “Make it great”).
• I don’t think Apple is bullying developers in the slightest.  If you don’t want to play by their rules, go develop for Android, webOS, or Nokia’s platform. Developers are making money on these platforms, too.
• The music business was a lot worse off then than the publishing business is now.  Publishing has a lot of options (perhaps too many options for them to parse, but that’s a good challenge to have, no?).  And, again, the competition isn’t going to stand still and give them time to catch their breath.
