Smart TV interfaces are almost uniformly worse than set top boxes (one or more of: bad UI, slow CPU, weird quirks, few updates) so you should avoid it anyway.
The current Apple TV (which I cite only because of familiarity) has a great UI, every major app, and robust HDMI-CEC support so you might never have to touch your TV’s remote again.
And Apple respects your privacy.
I was actually really pissed a while back because my in-laws were over and when I came home they told me "For some reason you hadn't connected your TV to the internet. We gave it your wifi password, and now it works!" Thanks. Now I have to change wifi passwords, and the power light on the TV constantly blinks because it thinks it should be connected to the internet, but isn't.
And you really believe that?
Consider that even the most trivial thing that makes Apple look bad gets leaked. If Apple was selling your private information, it would have leaked long before now. Also their financial reports show no indication of revenues that could be associated with private information marketing.
And regarding Apple - I hear this "not their business model" argument often but I see zero real life reasons why it couldn't be but we wouldn't know it. It is like saying that "John only trades tomatoes, it is impossible to him to sell cucumbers, it is not his business model". How is even related, monster corporations have multiple divisions with multiple business models, one doesn't exclude another.
PS: this is for the sake of discussion. Personally I also tend to think that Apple collects much less data than FAGM, and there were experiments that indirectly support this theory. I'm thinking about moving to Apple ecosystem but it is rather costly and will cause vendorlock. Not an easy choice.
Yes, I think most people understand this and say "selling data" as shorthand (because, for a lot of people, it's a distinction without a difference).
E.g. Some TVs will honor wifi off setting. Or alternatively setting the TV to use the Ethernet port.
Or if it needs something on the other end, set up old underclocked Raspberry Pi as a basic router/DHCP server that connects to nothing; power it with TV's USB port.
If you've got a fancy router, connect it to your network with a fixed IP and firewall deny all packets from/to its IP.
If you've got a fancy AP, set up an alternative SSID that connects to an unused VLAN or otherwise routes to nowhere.
(I'm almost astonished that advertising networks haven't switched to using raw IP addresses everywhere.)
The firewall has the same DNS block-lists as the Pi-Hole, but also has subscription lists of IPs to avoid. Most of those are spammers or malware, but can include whatever other category of malfeasance you desire.
With 5G, you will have the same problem. And I'd be very reluctant to buy anything stationary which has 5G connectivity.
I specifically bought a smart TV with Roku instead of whatever software Samsung/Sony is doing for these reasons.
Yeah, exactly for their users in China.
