It adds up when you need to pay $25 to get per-app volume control, $20 to fix to the menu bar, $10 to get window management, etc, per seat.

I don't think it's cynical to point out the perverse incentive. I think it's a useful point for discussion, especially given anyone familiar with any of the other major desktop environments (Windows, GNOME, KDE, etc.) might be surprised to learn that there's a modern desktop environment lacking these amenities.
