Whining
Let's stop with all of the disingenuous talk about these apps "mysteriously disappearing".
-Box Office was taken down because the name was a trademark violation(re Box Office magazine/web site).
-I am Rich was clearly a scam.
-Netshare creates a major grey area for AT&T, Apple and their customers. Tethering is usually a premium service for smartphones. I am sure that Apple has legally binding agreements with AT&T that apps that they sell are restricted from certain activities, and they need to show good faith in this agreement. Which means that letting an app slip through may not make them liable to AT&T, but leaving it up once they know about it will.
All three have legitimate concerns - only two of them are real apps, and "Box Office" is still available, it just has a different name. Apple is wise to take down NetShare while they figure out if it violates their agreement with AT&T(or abets AT&T's customers in breaking their agreements, which Apple could also be on the hook for).
And Nullriver is playing stupid here - they know full well why NetShare was taken down. They probably were amazed it got through in the first place. Don't get me wrong - I hope they DO allow NetShare for sale with full Apple and AT&T approval, but I can't get mad at Apple for meeting their obligations to AT&T.
I think everyone needs to give Apple a break on this one. The app store is a new thing, and there are over 1000 apps online in just a few weeks. If 1 or 2 get through accidentally and are quickly removed, just consider it growing pains. MobileMe was a bit of a debacle - but the app store is amazing and worthy of praise not criticism.
