The article isn’t entirely clear. I get the impression that the person in question may have been the sole maintainer for some hardware-agnostic parts of the wireless stack (which I’d expect to only need active development when a new standard gets greenlighted; should be bugfixes the rest of the time), co-maintainer of the drivers for some atheros chipsets, and the general oversight/coordination guy, but there are other developers working on specific drivers.
