The problem is that there is no good solution for tiling window management on OS X, even with third-party software. The parent may not have stated it that way, but you’re being over sensitive if you’re actually offended by their comment. Personally I feel like I’m using a toy when I have to use a non-tiling window manager. It may not be for everyone, but the display server or desktop environment should at least provide an interface to allow someone else to implement it.
