I'm not concerned with Apple refusing apps that do seamy things (though "seamy things" is more subjective than you might think, as Apple is well aware).
I am concerned with things like Apple's terms of service saying "If you put an app in the store, we reserve the right to copy it and ban yours."
Yes, there are more charitable interpretations possible, but Apple does have some history of cloning and killing off third party software, so I see no reason to apply the more charitable interpretation.

They don't spell it out quite that clearly, but sections 14.4 and 11.2 of the developer guidelines make it clear enough (https://download.developer.apple.com/Documentation/ADP_Progr...).
