Great points. From one perspective, we can't afford to do this stuff; from another, we can't afford not to. If connectivity makes your life a little easier for little risk, that's one thing; if your dishwasher steals your identity and sells it online, that's another.
My concern would be low quality, usually cheaper, whack-a-mole mfrs that come and go on Amazon, eBay, etc. Even if they release a product that would fall under these guidelines, how are you going to go after a ghost?
Another great point, but that's a snapshot of the market as it is now. We expect certain standards from some things but not others, depending on how much you depend on them, how much is at risk, and what the costs would be. Right now, under the proposal, a company is 100% free to say "I will support this for 0 days and you expect it to ship broken from the factory" -- it's just that they actually have to say that out loud.
Also, what happens when an IoT mfr is acquired, does the acquirer assume all the IoT risks as well?
I expect this to be a hot topic on the record. We'll see what technologists, manufacturers, consumer advocates, etc. say and try to come up with a proposal addressing stated concerns.
