I actually blame Johnny Ive for this clusterf*ck. Ive famously pursued a crusade for thinness. It's said that design is the art of compromise. Well, Ive took a no compromises approach to thinness and it showed.
Look no further than the 12" Macbook. One port (also needed for power), lower power CPU and (I believe?) the start of the dreaded butterfly keyboard. IIRC the butterfly keyboard's raison d'etre was to shave half a millimeter off the thickness of a Macbook. That's... it. Oh and that same crusade is probably a big part of why we lost the MagSafe adapter.
Compare the 12" Macbook to the (2010 and onwards) Macbook Air. A good compromise of thinness, power, ports and price point. For years, many (including myself) just wanted an upgrade to the Macbook Air with a retina display (and more modern ports). But we didn't, we got the "no compromises" Macbook instead.. until that was (thankfully) killed and the macbook Air came back.
And sure Ive designed the 2008 Macbook Air and he deserves credit for his design but... he clearly went off the deep end at some point after that.
The M1 Air even got rid of the stupid touch bar (thank God).
