This does raise the question if other Smart TVs with the same third party apps have the same issue.
In the article they mentioned that Amazon and Roku block apps from using these SDK’s, and specifically after Roku recently made a change to disallow this kind of thing, many of the affected apps were withdrawn from the Roku app store. The implication is that those other smart TVs don’t have the same third-party apps because these apps were specifically created to act as a foothold for these residential proxy networks.
Vizio was caught taking screen grabs and sending them to a server a few years ago.
The LG WebOS Store is a different beast.
Just browsing the list of apps raises eyebrows for even the most non-tech audiences. 99% of it is spam, with maybe 1% being well known apps like YouTube.
The rest are weird IPTV Players, Wallpaper apps. It feels like a portal into 2009 apps, but its not.
