"Is that situation getting better recently, or just always the same?"

Technically it is getting better, but not by much, and look at how long it took!

#Maltron (non-split but contoured) is from the 1980s or so, and still being produced.

#KinesisAdvantage (non-split but contoured) debuted in the 1990s, I believe. Still being produced.

#KinesisAdvantage360 (split contoured) came out 2022.

#Glove80 (split contoured) is from 2023.

You know what's funny? When one looks for a split contoured #ErgonomicKeyboard, it's the other way round: there are exactly TWO commercially available models - #KinesisAdvantage360 and #Glove80.

Last month, I got the latter. Previously, I used a #KinesisAdvantage, one of TWO commercially available non-split countoured keyboards (the other being #Maltron).
