It's either awfully shabby behavior on Apple's part or there's a critical (security?) reason for their having disabled your app.
Anybody got any thoughts on that?
All considered, it may just come down to Chronos's being the all time ultimate, sad sack developer.
There may be a critical reason but whatever the reason
the responsibility rests entirely with the developer. Apple has no moral or legal responsibility to assume support for unsupported third party apps. Maintaining the various developer certificates in good standing is entirely the developer's responsibility. To do otherwise could imply Apple would assume support of any application where the developer has ceased to function, a task no sane business would want to take on.
