You're welcome to disagree with the premise that fewer wires is better. I personally like their opinions but definitely not for everyone.
Now we've reached the conclusion of this discussion with a good old "well that's just like, your opinion, man" I would like to add that the magic mouse is not as popular as their other peripherals. In fact, at least in the office I work in, people would rather use a £5 Amazon special than one of the spare Magic Mice laying around.
the touch bar is not an optional peripheral so I can understand a bit more resentment there. I do however at least see where they were going with it (fn keys are too far from the home keys to be useful, few people use them anymore, we want to integrate touch without smudging screens and requiring awkward wrist angles). They happened to be wrong about most of that in a more objective way, but people act as though it's a decision made with the sole purpose to annoy people, or perhaps a the elites at Apple have become out of touch.
It's the sort of tech that would work much better as "simple" per-key displays you can configure. I imagine in their minds, it wouldn't be too dissimilar from that in the future with the right haptics and maybe some programmatic tactile feedback (for which the tech just isn't there yet).
