alt Hacker NewsI still have 4 of these, even one of their bluetooth ones. They all work, except a 15 year old one whose USB cable got frayed and fell apart. (I bought a USB-C port to see if I could fix it, yet another incomplete project)
I agree with op who said that they aren't getting better but calling it stagnant is more than I would say. The build quality was quite high and they clearly focused on that, and the price reflected that. I own another mechanical keyboard that I bought from Amazon during the pandemic and I already started getting ghost tapping (I only used it for dev work so I was more than a little annoyed to see it).
Not saying it is perfect though. They clearly were a Windows-first shop and that never changed. I've never managed to get the 変換 key and the other Kanji keys working in Linux or on Mac, much to my annoyance.
Often behavior like ghost-tapping, double-inputs, etc aren't actually an issue with the board, but rather with the switches. A lot of newer boards come with hotswappable switches which makes it easy to fix this without soldering.
Problems with the circuit board or the firmware it runs are certainly possible of course, but what I've seen most of are switch issues.
