I wonder how recently this has been implemented - I have a Samsung NU8000 bought in early 2018 that has no ads (not connected to Internet) nor spaces for ads.
I seem to recall it pestering me to connect it for a few weeks, then giving up with a whimper...
Thankfully, firmware can be updated via USB - and it did actually need one for an HDR brightness issue.
The problem is when will Samsung et al decide that no, nobody can possibly not have an Internet connection anymore, so firmware updates are only OTA.
Biting the hand that feeds IT
