If I open a store in my town and start selling fake crap I can’t go and say “sorry not my fault I’m just a reseller you need to deal with the guy who sold it to me” I will be brought to court and loose why is Amazon allowed to sell fakes and non UL complient equipment?
The problem with that is that vulnerability will be found and used. Since it’s connected to the internet it will be exposed to attackers and could be infected with botnet viruses/tools and used to attack other computer/services.
