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).

On the other hand, it eventually becomes frivolous to predict what/how people think. If it's an app store, it's any app store.

Can we have someone insert the word "Slack" into the title?

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.

I'm not going to flag it because I'm against censorship, but yes, this is an absolutely terrible title.

Isn't flagging just to bring the post to a moderator's attention? (who can then decide what to do) At least that's how I've always understood it.

If many people flag a post or a comment, it disappears, pending moderator action. Which is a bit unfair if the wrong title was a honest mistake.
