Has to be proven that it occurs first I suppose. But it would also be a difficult thing to workaround. Like in your example the only thing stopping them is a firmware update that dictates the tv connect to as many other clients as possible and blacklist clients that can’t receive a challenge code or success packet or something

Of course I’m sure if that happened people much smarter than me would spoof all that too, make a spoofer that creates dozens of pseudo devices, break challenges and such, etc. cat and mouse game. Luckily these things are usually super lazily implemented by the ad scum but frustratingly that’s bc dedicating resources to this is not worth it usually (eg many people, a sizable and increasing percentage of users, may simply not connect their tv to the internet but once a raspberry pi or docker container or whatever is involved you’re in strictly nerd territory)
