Worst part is, now you can't find a dumb TV anymore. The closest thing out there are "commercial signage displays" which are just dumb TVs with limited inputs and usually without remotes, but 25-50% more expensive because "commercial" (and because they won't be able to continue making money by showing you ads and selling your data) and a lot of retailers won't let you order one without a business account, or force you to order in bulk.
And every Neanderthal I complain to is like "but smart TVs have so many more features," like, bro, I can make any TV the smartest fucking TV in the world by plugging it into the desktop PC I'm gonna keep right next to it anyway. All the "smart" bullshit just gets in the way. I've yet to encounter a smart TV UI that didn't require a dozen button presses to change inputs and spend two seconds or more re-drawing the UI with EVERY INPUT because they put the cheapest processors they can find in these pieces of shit.
