I'd say you just don't need to narrate being huffy with them. Express that you are upset and why (as you did) and just leave the announcement that their media sharing attempt failed left unsaid because any reasonable person can figure it out and the conversation is no longer really about that. If they somehow need to ask or are oblivious, then of course there is no begrudging you giving such an account.

At least, that is how I would personally approach the issue since you express uncertainty of how one could.
