Because WiFi speeds have increased to the point where they rival wired connections, and most people use laptops which make wireless more convenient.
Wired nowadays only makes sense if you need to move massive amounts of data, want to use PoE, ...or are in a high interference area. Kind of ironic they'd design a building that makes it the latter.
At least in my faang office, there's essentially zero ports to plug into. If you have a desktop, there's a port, but that's the exception. I've never seen anyone plug a laptop in.
