Is the plan of action "eliminate all public IP cameras"? That's coherent, I'd get it, but that doesn't seem to be what he's saying at all. He used a Google search to find exposed Flock admin consoles (interesting! say more about that!) but he could just as easily have just searched "open IP cameras"; there's sites that do nothing but index those.

If your takeaway from that comment is that ‘tptacek thinks Flock’s tech is old news and he’s resigned about it, I think you’re going to be in for a treat.
