I guess the actual, underlying problem is, the Touchbar is bad UX for a bunch of software engineers, but pretty great for most everyone else. Think about it – you lose some keys you never really had a use for anyway except as media keys, and you get almost analogue-ish volume and brightness controls, apps can give you context-dependent options that are really discoverable (which F-keys totally aren't) and can adapt to your feature use patterns and be a lot richer than static bindings on 12 keys. As a musician, you get a neat little slider – no replacement for a proper external controller, but it's always there when needed, and it can change its behavior dependent on the context. As a photographer, you get a multi-function slider in post that feels (to me) a lot more precise than any touchpad acrobatics I'm capable of. Plus, and most importantly by a long way, it makes emoji really usable on MacOS, and emoji are super, super important stuff, it's hard to overstate their value. Text-based communication loses a lot of emotional cues, that's really hard to get used to if you're used to mostly in-person communication or at least voice, and in my experience keeps causing small (or not-so-small) misunderstandings and microdose vitriol even among people who have been doing this for ages and ages, been socialized in it, aren't too keen on lots of face-to-face, and detest emoji with a passion. Those are things that make the Touchbar a pretty neat feature for lots and lots of people, even given its many "legitimate" issues (it tends to micro-freeze for some people, it isn't as precise as it could be, lots of apps use it in not-well-thought-out ways, it's very hard to use blindly, ...) But not having F-keys is so disruptive to a lot of deeply-ingrained software development muscle memory and UI conventions transplanted from other OSes and other decades that I guess it just wouldn't fly with this crowd in pretty much any shape and form factor.
