But is it not potentially a DOS? The Good Guy publishes an entry. The Bad Guy copies the atom:id of that entry into an entry with different content, gives it a later atom:updated, and publishes it. The aggregator stops publishing/displaying the Good Guy's entry and instead publishes/displays the Bad Guy's entry. Thus, the subscriber doesn't see the Good Guy's entry (unless they saw it before it was replaced).
Technically, yes, it is denial of service. But the term "Denial of Service" refers specifically to attacks where the main objective is to prevent a service being accessible. Replacing content does deny service, yes, but it's also a lot more than that.
