Maybe the right solution was to not revoke the current app and just upload the fix? If it was a security bug, that kinda sucks for security, but if the cost is being locked out of your developer account, that might be what developers need to do going forward.
Maybe, maybe not. It sounds to me like they revoked the app because they didn't want users to suffer a critical bug until they could put out a fix. I think that's a good thing and I see no reason why it should trigger an investigation, but we'll never know because of Apple's lack of transparency.
