It’s about the pentaprism, as it is heavy and adds to the manufacturing cost rather significantly. There is also a patent for the instant return mirror which has to be paid for and the owner is Pentax.
I think the mirror less camera are about weight. I looked at the Sony
full frame A-850 when it came out. It was quite heavy compared to my Minolta
full frame film cameras. I have always shot with at least two ( sometimes three)
35mm film camera around my neck. Two A-850 bodies and lenses around my neck
seemed like too much weight.

I think it has been ascertained by RIT (among others) that rangefinder
camera/lens combos are sharper because there is no mirror box in the mix.
Mirror less cameras are just something else for the conglomerates to sell you.
Manufacturers put an awful lot into sales pitches, and humans are such
suckers, we bite down on all of it. It’s not about technology, it’s about
product sales.
