In the context of a $4000 Mac Studio with something like FinalCut Pro allows them similar creative power that the inaccessible, siloed $10,000 workstations.
You're much more likely to see a Mac Studio in a school, library or computer lab where underrepresented people live. I had a gig a few years ago that took place in a public library with a lab of trashcan-style Intel Mac Pros, which were more expensive and far less capable than a Mac Studio.
It's not a waste of money when you bring expensive equipment to tens of thousands of people to use.
A single $4k computer for a 1000+ student school should be an afterthought, spread that cost over 5 years and the cost per student is minuscule. This is not a Chromebook you get for every student, you'll need one or two max - unless the school specifically focuses on A/V production.
This is equally true for a $10k computer, spread over all the students. It's great to save money. But Apple's diversity claim just doesn't add up.
