"register their interest"
I wish there was a way to register my disinterest, other than not buying any of this crap of course.
Sometimes I'm glad I'm old. Not always, there were some advantages to having a properly functioning body.
I know da yoof (proper Dad speak as I understand it) are entitled to enjoy and make use of things my generation don't 'get' (I did when I were a lad, sorry dad), but all this IoT stuff is mostly bunkum and insecure to boot.
Maybe one day it will be okay, but given the mission creep by companies wanting ever more detail about my life I doubt it.
