I don&#x27;t understand why people have a problem with this. It&#x27;s sleazy, sure. But clients should never trust the network.<p>The fact that this is happening is due to protocol and software faults that need to be fixed.<p>Once your network client can no longer be fooled with rubbish inserted by someone who happens to own some wires, then fake responses become a simple matter of bandwidth and QOS agreement, like dropped packets.<p>The fault here lies with the developers of insecure network client software.
