Why do you want a not-smart tv? I thought the point was to not have tracking, but you were using a Chromecast dongle and I would expect Google of all companies to keep track of what you watch at least? Is it the security risks that probably show up after the tv software stops updating?
Here's another thing that shits me about the TCL. It asks me to sign in when setting up for the first time. You can't skip it. I thought this was related to Google TV, but apparently not. I later found a way to log out of the TCL, and my Google stuff still worked fine. False and intrusive behaviour from TCL.
Also! your average joe would think this is for the Google account and would probably put in their Google password. I found an option to use a link number instead. How many Google passwords have been exposed to TCL?
I would guess Google's privacy stuff is still an order of magnitude better than the TV manufacturers. Google actually gives you a decent amount of control over your data. There are definitely better privacy options than a Chromecast, but I don't think it's fair to put Google in the same category as Vizio/Samsung/et al.
1. The old Chromecast dongle is much faster than this new TCL TV.
2. Google already knows everything I do and I trust them more than TCL.
Playing a stream from the dongle just freezes after 30s. I'm pretty sure it's the TCL hdmi implementation, because the dongle has been utterly flawless previously.
