I like the idea of UL testing for at least basic security vulnerabilities.
Vulnerabilities are often trivial in hindsight and lost in a massive forest up until the moment they are serendipitously discovered.
I'm not saying a proper audit shouldn't have found this and flagged it. But yes, agree strongly, vulnerabilities can be surprisingly hard to find.
I see it as analogous to FCC certification of RF related equipment.
This does a few things.
1. Secures endpoints down 2. Chains users to company 3. Makes cloners hard to copy product, given server based logic
Hell, Google and Microsoft can't even bother to keep up products or their DRM up for any length of time. But again, users are willing to rent chained devices like the Nest.
Instead, how about ISP supplied modems/routers have sensible defaults(and have the admin password reset)?
Much more cost effective.
