Many newer smart TVs will literally not boot up past a certain point until you connect them to the internet to "activate" them. It's actual madness.

It takes ages to boot, might have integrated offline ads, draws power when on standby for features you don't want like remote controllability via network, and it'll probably nag you forever to let it online. No thanks, a display will always just be that in this household. Separate concerns please, also easier to upgrade or replace.

I set up my Samsung give it its initial update, and then blocked it from internet at my firewall. If I need it to do something I unblock it for a few minutes and then block it again when I'm done. I use streaming sticks for all my other work and they're just pie holed regularly.

That's what I did with my brand new whatever-inch big fucking flatscreen. Like 80% of the buttons on the remote make a little notification come up saying the feature's missing since the TV wasn't set up "properly", but it works fine.
