@frigidcode Whle I am not @dangillmor and don't have a "smart" LG TV, I do have "smart" Vizio TV, several Rokus, and a Pi-hole using the Smart-TV Blocklist[1] with RegEx extension[2] in addition to the Firebog Ticked lists[3] and block cloudservices.roku.com to return my Roku home screen to that of a streaming media player rather than an advertising screen.
I don't use the TV for streaming, but have it configured to do so and leave it connected by Ethernet so that I can control it from an app, cast to it, receive updates, and be ready to stream if ever I so wish. Despite this and the fact that I have it configured for as much privacy as permitted, the TV is constantly trying to connect to many external services. The Pi-hole blocks many of the connections.
While I do not know if the end points for LG's spyware are blocked by the aforementioned lists or if LG tries to circumvent local network policy by silently using its own name service or other measures, I would expect DNS filtering with suitable blocklists to be mostly - if not completely - effective against the spying... for now. The significant majority of the audience will simply connect this (and every other "smart" device) to their only wireless network and click through the initial setup process as quickly and carelessly as needed to get to the streaming.
