OP's indignation and discontent surprise me. Any device, be it a hardware wallet or a smartphone, must first of all perform its basic functions, be convenient and easy to use. For most users. That is why all hardware wallet primarily work with the Windows OS (as the most common), and not with Python. Although almost all devices work fine with Ubuntu and Mac OS.

I don’t see anything wrong with the fact that any manufacturer (of any gadget) is trying to make their devices prettier and more attractive in order to sell better. Nothing personal, it's business. Each manufacturer also strives for cheapness in order to reduce their costs and increase profits. Nothing personal, it's capitalism.

Not many devices have a touchscreen. Not to mention big. Most often these are small monochrome displays.

If we strive for mass adoption of crypto currencies, then hardware wallets that allow to store, pay and send crypto should be as easy to use, cheap and minimalistic in design.

Look at the HW market. Such devices already exist. What annoys you about them? Choose the one you like best and that's it. Or create very best hardware wallet your in the world.
