As someone who designs IoT devices like these for a living, the device manufacturers here are in many cases the smallest companies in the supply chain and have very little ability to influence things upstream of them, especially for specialty products or companies entering a new market. It's often a major win to get a chipmaker to pick up the phone and sell us their product, much less receive any support at all. I wi…
If it was forward looking, rather than retroactive then it would at least mean that chip manufacturers wouldn't be able to sell their undocumented/unsupported crap because all the buyers have to have it? If there are no buyers then their attitude should change.
Since the specific "IoT device for the USA market" set of buyers is actually a small percentage of sales for most of the parts they sell, they really don't care to support their product from the IoT security perspective. This support is expensive, so it would very likely be cheaper for them to ignore the market completely.
