Monotouch has been out since November 2009, Adobe CS5 isn't out for the iPhone yet, and as for Titanium I don't know the exact time period but it's not been long. The only platform producing apps for a longer period of time has been Unity3D, which now advertises itself as having over 600 appstore games. So your argument about raising the barrier to entry is weak, as these tools have only just emerged in the last 6 months. Prior to that we've seen thousands of poorly written, leaking objective-C applications on the AppStore. I've seen 2 RSS readers and the official digg.com app crash straight to springboard in the last 2 weeks, all written in objective-C. Just because the language is closer to C and enforces memory management doesn't make its barrier any higher or require any greater skills - it means you'll get a tonne of apps that aren't releasing or reference counting and crash. I'm sure all this was hotly debated 10 years ago and garbage collection won.
