Why don't people like their Smart TVs? I've had a 4k smart TV for years and love it. Being able to stream without needing my phone is great. It seems ironic that people are complaining about smart TV ads while the [2] link in the OP has an absolutely MASSIVE video ad that takes up 2/3s of the screen. And it's not like you're not being tracked when you stream from a Roku stick / Chromecast. Edit: I have a 4k Samsung t…
[1] Having an ad on a web page about concerns with Smart TVs is not the same as the TV manufacturer selling ads on your TV. For one, it's just one more opportunity for the TV to fail. My smart TV won't load its' UI enough for me to select an HDMI input if it can't connect to the internet.
[2] Again, there are levels of tracking. I don't know about Roku, but I imagine when you use one, you have tracking from Netflix while watching Netflix, Hulu while watching Hulu, etc.. At least, this is my expectation of my Apple TV. If you're streaming to a Chromecast, you can limit what it sends to Google.
[2] None of this has to do with the fact that a manufacturer can apparently brick your TV remotely, and while this is meant as an anti-theft measure, it's pretty easy for them to accidentally include your valid serial # in a CSV or whatever. I'd imagine un-bricking it is very difficult, if even practically possible.
All in all, over several years of having Smart TVs, I've still not ditched my Apple TV or Chromecast, and I find that both tend to give me higher quality, though I expected the inverse by avoiding dependence on an HDMI cable.
Smart TVs are also amongst the most notoriously poorly updated smart devices, and over time this becomes a risk to your entire home network.
