I think what you're suggesting is that enough bricked devices will cause consumers to demand security - maybe even some measurable metric, like a certification of external audit - as part of the standard product search.

But I don't think bricking a device necessarily ties into security in people's minds. If they permanently modified it to always show HACKED_BCUZ_DLINK_SUX whenever I try to load the camera feed, sure - but a bricked camera is just a failure. I don't even know if it got hacked, or if a capacitor blew, or if a rodent chewed through something crucial.
