There must be more to it (even if just he is 'anti-wireless' despite what he writes) - the points in the article would be trivially addressed by a cable fallback option. Less trivially by using Bluetooth (so standard and built in to many computers, esp. laptops) and AAs (so the optionally rechargeable batteries or also standard and purchasable from 'anyone'). Not that I'm bothered, the keyboard is probably the last thing on my desk besides my monitor that I'd try to ditch the cable from. On the whole I think I prefer them to faffing with Bluetooth, and easier to KVM. (For stuff that's on my desk I mean - I have AirPod-like earphones from Anker (about ⅒ price for no discernible disadvantage) that I wouldn't go back from, and used a Bluetooth receiver with 3.5mm jack before that, in particular to decouple my ears from my legs while cycling.)
