Except if you penetrate the market with modules that cost 5% of similar US made solutions, you start to win mindshare. At least some of those hobbyists start making a product, and sometimes the determination of whether a product is "safety critical" isn't agreed upon until after it's failed catastrophically.
They are definitely beyond a hobby device.
They're made well, designed well and the libraries are some of the best in class.
My concern is purely on risk.
What would any responsible state security agency spend to have devices behind every single firewall of an adversary?
