I really hope these are April fools jokes. Matias is charging $600 for their normal, full size keyboard the only difference being Tap mod on spacebar to enable a second layer. That is a $450 premium for QMK.
Sadly it looks legit and like they are targeting the disabled, meaning they can charge this because stupid institutions will buy it.
This is just as bad. It is like charging more for a thong than full underwear. Half the fabric, twice the price!
One half of a laptop keyboard with QMK for the low price of $600.
