Would be great but the manufacturer would be at a disadvantage because that bundled bullshit effectively subsidizes the device. So you'd have to either raise prices or accept a lower profit margin.

Due to the high barrier of entry (e.g. because of patents) it's unlikely that a privately owned company can make a big market entry, especially across countries. And a public company will be forced by the shareholders to maximize profit so either you bundle crapware or they fire you as CEO.

Of course if you look outside the TV market such devices already exist. High-quality digital signage devices can easily be had – for about three times the price of an equivalently-sized TV.
