Ummm... The strict uniqueness of app names IS enforced by Apple, unless you're saying that "Color!" and "Color+" are the same app name. How would you expect Apple to enforce such a policy, anyway? Is "Sky Cloud" the 'same' as 'My Cloud'? Who should make such arbitrary decisions?

As far as "Apple doing nothing about it"... Why does this even matter? If your app is in the top 5, being viewed by thousands of people who presumably then click on it, why would you think that a similarly named app that is not in the top 5 receive any attention? If the developer of the other app was able to make money piggybacking on your sales, I'd love to see your sales chart clearly demonstrating this effect, and I'm sure Apple would as well. They're out to make money, too.
