Have one of them from TCL. Never connected it to the internet after just skimming the Terms of Service. It basically says they can monitor the contents of your screen at all times and use the data for any purpose. This TV was primarily for work so that's completely unacceptable.
And TCL is a Chinese brand (like Hisense) so it's a double whammy of possible "accidental" privacy invasions.
Samsung are just as bad if not worse with Tizen, it has giant permanent ads (maybe you can block them via your router) and it has/had an NFT store
In the UK there used to be JVC (and other cheap brand) "Fire" TVs with a firestick built-in similar to the Roku TVs but they seem to be going away and those and other brands (JVC, Sharp and TCL to name a few) are now all Roku TVs.I think it's partly because Pansonic have Fire in some of their 2024 models (non-OLEDs probably) and also Amazon just has a TV of their own called "Amazon Fire TV" but I don't know who makes it, probably Vestel or TPV/TCL.
There's a crazy amount of tracking in TVs these days, I sell 75" that's £699 lol even tramps can afford it so they'll easily get one in every home soon enough, I've heavily facilitated that as well, oops gotta pay the bills
oh well at least some people who'd normally buy entry level okay TVs have MiniLEDs or OLEDs now.
