I'm not sure you do. Or at least you're replying to a very uncharitable interpretation.

From my perspective, this read as: the moment you put one of these IP cameras in a room, you should assume you're now in public, no matter what assurances you might have from the manufacturer or what safeguards you might have put in place. So if you intend for a particular space to remain private, don't put one of these cameras there.

> it is their fault because it is "public"

From my reading at least it didn't seem to imply that "it's the camera owner's fault", or that they should know better or that they deserve what they get, etc.
