I'd like to see someone actually name & shame the devices involved. With evidence, of course.
I've had a quick poke around my house, and the couple of devices I have (wemo, philips hue) are holding pretty persistent outbound http connections - not dropping their trousers and exposing telnet.
Persistently exposed telnet sounds more to me like industrial control devices, network appliances, etc. But "IoT" is so vague that we're immediately jumping to blaming consumer devices.
