The thing is that it's not about what you think the product should be, because the product won't morph itself into your desire. Just because there are 100 variations of the same monitor out there are all behave nearly the same (And might as well be condensed into 1 version with 2 bezel color options) doesn't mean that that is all there is to it.

The ECU in your car uses the same SoC as the ECU in a truck. But that doesn't make your car a truck, or a truck your car. Just because there are technical similarities doesn't mean that therefore the products must be the same. If a manufacturer decides to focus on some form or function and simply not make other forms or other functions, that simply means that what you wanted and what the product is do not match, and therefore you should either not buy the product, or adjust your wishes. Since the latter isn't really required, not buying the product, but buying a different product instead seems to make the most sense to me.
