Re: Will they go far enough?
That's actually not a bad idea, commercially.
People who've already bought IoT tat are the most valuable market segment there is: early adopters. People who are curious or jealous or vain, or just have more money than they know what to do with. People like that are very likely to buy new gear anyway within the next year or two, even if their old stuff is still working just fine - so maybe there's little to lose, and much to gain (customer loyalty) in helping them to run their old equipment for as long as they like.
