Revolutions need to start somewhere
If us with the sort of knowledge and experience say NO, NO and NEVER to this sort of crap loudly enough AND when our friends and reliatives buy this shit and turn to us for help, we say 'No Deal. Get rid of that thing first, take it back to company that sold it and demand your money back", we have no hope in hell in stopping this invasion.
We don't have much hope without the lawmakers getting involved and even in the USA the FCC has decided to turn a blind eye to this problem.
None of this stuff (even if it has a 'homekit' stamp of approval) will get installed on my network EVER.
