What Apple policy bans Qt-based apps from the App Store?
I haven’t seen it.
Only the US DoJ or FTC could make a dent in this joke of a review process.
I feel like enforcement is rather random though. It seems like submitting updates draws their attention.
But you could be right. It may be it's a rule they abandoned.
In any case I don't think there's anyone around with the heart to try again.
