imho adb works wonders debloating many smartTVs. mine shows zero ads outside of commercial tv breaks. not even suggestions for amazon shows or anything in the dashboard. smarttube,kodi etc are just great!
You've gotta realise the average joe doesn't know how to do any of that stuff though. Even trying to explain it to most people is too much. The frustration I find is, most people don't actually want to learn, and they'd rather stay ignorant, and basically take pride in it.
