> You do have to pay a premium for them, for a variety of reasons.

It's not that you pay a premium for the bullshit-free version, but rather that you get a discount for buying the bullshit-packed version.

Another data point: Before all the smart TV stuff you would tend to pay significantly more for an A/V monitor (basically a TV without the tuner) than you would for a regular TV.

Both statements are true. As a baseline it's good to consider the price of the regular TV's before they got smart.

You do also pay a premium because they use use panels designed for 24/7 operation, sunlight readability etc.

When talking about digital signage in particular, it's clearly a premium because it's such a big price difference. A discount for the bullshit would be much smaller.

Digital signage have embedded computers now too. It's only a matter of time before they have mandatory analytics and advertising.

TVs intended for digital signage usually contain modular computers meant to be controlled by the user.

You seem to be downvoted by ad haters - ads being a sensitive topic - but in the context of a device made specifically for delivering ads, I agree it seems like a good idea.

In the context of being a reasonable human going about my business - I wouldn't want one anywhere near me.

Why would a business purchase a digital signage display that forced them to show someone else's ads?

I think they got downvoted because they misunderstood the idea. "mandatory" analytics and advertising would be working for the manufacturer, not the owner. To be an (antisocial) value-add it would have to work for the owner.
