Will it have preloaded ads that will never change because it can't download new ones? Will there be huge gray boxes where the ads should be in the UI? Will it try to connect to open WiFi or use HDMI to share my streaming box's internet connection? Will it nag me with an alert box in the middle of the screen asking me to connect it? Will it disable features if I don't give it internet access? Will there be bugs and performance problems requiring me to update the firmware, and if I do, will that firmware update introduce any of the above?
Generally, firmware updates on modern TVs are used for creating bugs and performance problems, rather than fixing them. They also add advertisements. Don’t ever connect it to the internet, and it’ll be fine.
The only downsides are that, being a smartTV, even in this pseudo-non-smart mode, if the TV loses power (rather than just being in an "off/standby" state) then it takes a bit longer for the TV to start up the next time. I wish I could avoid a TV having a "boot sequence", but my experience is close enough to a non-smart TV that it works for me
Granted, none of this has happened yet... but when it happens, I'll start busting open my devices to disconnect any and all antennas.
Maybe it's just an outlier? It's certainly slow, though.
Although it wouldn't surprise me at some point if Samsung or other makers started bundling cellular modems in or had deals to have them automatically log into the "free wifi" for the major cable internet providers :p
I'll agree on Samsung's end though. Everyone's Samsung TV I've ever tried has been stupidly laggy.
