Yeahhhh I had to disconnect mine from the internet due to this (I don’t want a display ad on the menu screen when I turn on my TV like WTF, my TV just enshittified itself randomly with an update that added this a year or two ago). Which would be fine but you can’t change the TV menu tile layout if you are disconnected from the internet… Just incredible layers of design stupidity here.
I use pfblockerNG(like pi-hole but for pfsense) to block ads to my roku. And I set up pi-hole at family members houses to block ads and telemetry on theirs.
