While I'm willing to give credence to your theory, at best I think the touchbar is "meh" and at worst is a net negative to the experience. We've seen Apple backpedal a bit already by introducing a physical escape key.I think you're overestimating how many people hate the touch bar. I see this on literally every tech forum i'm on. People think because most people on the tech forum for enthusiasts hate/love a certain feature, that the general public feels the same way and it's almost never the case. I'm not saying everyone loves it either, i'm just mainly saying the assumption that it's this widely agreed upon hated feature (like the Butterfly Keyboard is because it's actually outright broken) is an echo-chamber effect and not because everyone actually feels that way. If anything, i'd bet more people feel completely neutral on it rather than actively dislike.
On a personal note, my issue with the touchbar is that it doesn't really bring more to the table, and sometimes makes the experience worse. The Volume and brightness sliders come to mind immediately, instead of pressing a key on the keyboard, one has to touch the icon, then use the slider. Is it a major hurdle? No, but it doesn't add anything special. The best use I've found for it is using BetterTouchTool to make buttons to run Photoshop scripts, and even then the benefit is dubious over custom keyboard shortcuts.
And, let's not forget the occasional glitchiness. There've been times that the touchbar becomes unresponsive for a second or hiccups. Minor issues yes, but it's a net negative when there's no real benefit to having the darned thing in the first place.
And if you use an external keyboard at all, the whole thing becomes moot. Any muscle memory you have won't transfer over to the built in keyboard, or vice versa for the external one.
Maybe it's not widely hated, but I don't think there's anyone singing its praises anymore.
