I agree, unfortunately.
When I began playing many years back now, I always heard the UI was horrible and counterintuitive from video game people. This never matched my experience playing, which was that the game quite effectively conveyed a lot of complex information, with the restrictions of graphical style being used. I also never really heard a complete or compelling argument as to why these people believed the UI was so bad, and it eventually seemed to me they were all just repeating each other as a way of seeming knowledgeable about something they probably had little practical experience with. Like it was the one insight you could point to to show you knew about this esoteric game. This criticism was so widespread I overheard it a bar in Toronto, also by people who seemed to have very marginal knowledge of the game otherwise. Even on the forum, my memory is that most people who posted here were quite comfortable with the UI, while admitting to a bit of a learning curve.
Eventually I noticed Tarn develop a sort of apologetic, self deprecating attitude about the UI, which he did not deserve in my opinion as I think he did a rather good job.
DF was a great game to play on a laptop, where you might not have a proper mouse. It was also nice to not use the mouse after working, as drawing and other computer work strains the arm in a way the keyboard does not. It was also fairly unique, whereas now the menus feel a bit more generic to the genre that DF started.
So, in my opinion, a real degeneration. I still have the old version around somewhere, which is still fun so no big deal.
