That's why GP mentioned "Smart TV".

A random Internet-connected smart plug made by KOCKJAKD and sold on Aliexpress? Almost impossible to catch.

A major brand like LG, with US presence and sold in brick-and-mortar stores? Much more possible. It also makes a much juicier target for lawyers, thus making it much more likely to get sued. And once there is a precedent, other manufactures would be in danger too. Hopefully after losing a whole bunch of money, the manufacturers will start cracking down on those residential proxies.

(Except that discovery is going to be painful. "Use discovery to find out what's on the other end" is easy to write, but in practice it means regular people dealing with bailiffs just because they happen to buy wrong brand of smart TV)
