I've never had this issue with Apple's monitors btw, someone there insists on having the ports flush with the surface at a right angle so it’s really easy to plug cables in.
CRT monitors also used to arrange ports that way.
The thinking of other manufacturers is probably "what if someone mounts the monitor flush against a wall”... however I’m struggling with a curved screen here, unless you live in a missile silo you probably can't mount that flush to the wall.
