> the Bloomberg Terminal constantly undergoes UI changes, though not in a dramatic way

This is correct. (Source: I worked on Bloomberg's UI change management policies.)

Despite dismissive comments from design industry folks and more modern-looking competitors, the folks who ran Bloomberg's UX team maintained a focus on customer needs and user research. There are even a few cases where function teams went back and re-implemented old "bugs" after a rewrite (e.g. in the MSG editor) because users had adapted to the old behavior. (Thankfully nothing as bad as spacebar heating https://xkcd.com/1172 though)
