One's personal feelings about COVID aside... The apple culture is built (and has always functioned) on human collaboration hence the building of the spaceship Apple Park with the common areas in the middle and throughout. Virtual interaction is not the same as face-to-face. If employees don't return to the in-person office, the company culture will suffer irreversible damage, and by extension, the products will get worse and worse.
You can get a dozen people in Zoom a lot quicker and easier for a "face to face" than trying to arrange a meeting in a conference room.
