not only are they half-assed incomplete attempts to solve problems solved by private offices, they ignore the excellent solution to the problem open-plan offices were meant to solve: using a small office space for a large staff.

if you let people work from home if they want to, you need far less office space. so instead of trying to cram in a ton of workspaces, just let people who want to work from home do that, and use the space that frees up to give private offices to the people who want to work at the office.
