You can 100% still buy them. They’re just prohibitively expensive for the average person. Business/commercial TV displays don’t require Internet connection. They’re often used for things like digital signage, corporate meeting rooms, etc… But they’re going to be like 2-3x the cost of a consumer-level TV. Because the price of modern consumer-level TVs is heavily subsidized by the fact that the company is planning on selling your data.

As a bonus, lots of commercial TVs have quality-of-life things like built-in WiFi casting and Bluetooth controls. The WiFi is just for casting, not for data collection and telemetry. Because no company in their right mind would sign a privacy policy to allow potential trade secrets to leak because a smart TV is using OCR to send screenshots back to the TV manufacturer. Because when you’re using them in a meeting room, you want any of the corporate people to be able to mirror their laptop to it without any hassle. So casting to them with your phone or laptop is usually straightforward.

Maybe we should Boycott TV'$ altogether? We have the internet, we have local free AI models, we have the ability to code and draw.

Not with that attitude you won't.
