I apologize if I&#x27;m incorrect, but I believe English is not your first language. There is a difference between opposition and conflict. It&#x27;s a bit subtle but it&#x27;s very important in this context.<p>When you say a &quot;malicious client&quot; you are misunderstanding the purpose of my analogy. A malicious client <i>would</i> be &quot;the enemy&quot;. I&#x27;m talking about a client that is interested with engaging with the service, not just shutting it down. The client may <i>like</i> to have all the information and resources the server has available to it, (for example, perhaps a facebook user might want to see when people look at their photos, not just like&#x2F;comment) but the server needs to consider the experience of <i>all</i> the clients and users, not just the one. So there is opposition (but not conflict!) between the two. The client will not be allowed to have this information, even though the server has it. Conflict would be manifested by the user abandoning the service (or attacking it, as in your example) because of this incompatible or insurmountable difference.
