I'm guessing it's because most women carry their phone in a bag, so the bigger phone isn't inconvenient and has the advantage of the bigger screen.
And I suppose most men prefer the bigger screen size, and they are convenient enough in the available sizes. I use a 6.7 inch, and it fits fine in a pocket for me.
Also note that although we have way bigger screens on modern phones, the bezels are way smaller, on the first smartphones the screen was only about 50% of the front face. So a 10 year old 4 inch phone can be about as big as a new 6 inch.

I just want Star Wars style comlink. Wearable on my belt or neck, with a strap in case of dropping it.

Will have to be a bit bigger, to have enough keys. And some display, preferably monochrome text-only.

But in general it should be a device not emitting horrible blue light all the time.

About form - I think something round with keys on the sides is still a good idea.

Phones are already too small. I use a fold because it's the only way I can get a decent sized phone now!

I mean, we are the customers, we choose, personally I went with the iphone 15 pro, because the max is just ridiculous even though I am close to 2 meters tall and have big hands.

If people bought the smaller versions when they are available I am sure phone makers would react

Probably for similar reasons we can't go back to small cars: People are getting older and can't handle them.

ETA: Old people need giant text so they can read things. Big screens show more big text. They also don't want to drop down into a small car, so they buy SUVs and trucks. So they make SUVs and trucks and great big screens for the old people who are most of the population.

Source: I am an old person. Except I drive a small car because it's fun

we can't have small phones because the os design can only be so flexible before it starts either being crap at every size or having so many edge cases that internally it's stupid complex.

having limited sizes means the sizes they do have can be well covered

There are small phones. There's more small phones than big phones. And I have big thumbs so stop whinging about the minority.

Edit: Omg I just lost to clickbait. FUCK.
