I agree, particularly because this covers a specific narrow case: the directory won't showcase/feature you, but the app still works. That's not what happens in the classic appstore, where a rejection typically means you're dead in the water - or forced through alternative means like AltStore (which is what I was interested in when I clicked the link).
True. However, the same strategy - "Focus on alternate sources of lead generation" can be applied for applications on Android (and presumably other platforms) where 3rd-party app repositories and sideloading are supported.
