My impression was that they used some slightly chattery Cherry MX keyswitches combined with a controller with a poor debounce routine. (The electrical output of many switches "bounces" quickly on and off a few times when changing states. This can cause dropped or doubled key presses if not accounted for by the keyboard controller.) I’m not sure if the batches of Cherry MX switches they had were bad, or if some amount of chatter is inevitable given the switch design.

From their marketing it looks like they have changed to (Kailh-made?) switches that use a light sensor instead of an electrical contact. https://trulyergonomic.com/ergonomic-keyboards/best-truly-er...

I guess that’s one alternative to implementing a better debounce routine.
