While all that sounds reasonable and perhaps possible, I'm not sure we need to call them "dumb ass designers"
I'm sure Apple looked at this from all angles and made a decision that makes sense for their priorities, in the context of what's possible product and business wise at this time.
I hold a B.A. in Industrial Design and an MFA in Concept Art, and I currently teach industrial design at a university. Sadly, my diplomas don’t come with a mythical blessing from Odin All-Father, proclaiming, "Whosoever holds this diploma, if he be worthy, shall wield the power of Thor."
Apple has a history of poor product choices, such as using materials that don’t last long, like leather phone cases that fall apart after a few weeks, or replacing them with woven cases that last only six months and are then discontinued.
Their iPad Pro cases leave the pencil prone to falling off the edge of the device.
The Touch Bar on their laptops was a terrible design choice that they reversed by switching back to regular keys.
The Magic Mouse has poor ergonomics and a poor charging port design. Apple chose the aesthetic they thought was best, which is also terrible to use.
Today, designers are often eclipsed by marketing teams obsessed with profits and social media hype. You see it in flashy, impractical projects like Kanye West’s Adidas collab or Virgil Abloh’s Mercedes-Maybach—a car that looks like a toddler’s sketch, likely a painful ordeal for the design and engineering teams.
Jobs was very demanding as far as they say about him pushing the teams to make things possible and doesn't roll out what is available at hand.
PS: I added the car that I mentioned above.
