The goal of this arrangement is that Apple will know who created a certain application if it causes problems and users will be able to tell, thanks to the digital certificate, if the app has been altered in any way for example, if a hacker distributes a modified copy of iWork with malware inside.

While Apple does take complaints seriously and will blacklist known developers who distribute malware, it is very possible for a new developer or an existing developer with a new alias to be registered and distribute apps with malicious intent. With this new model, any tampering with an app would render it unlaunchable.
A developer signs up for an account and gets a certificate. Apple never sees them.
