From the link: "Note: The inbuilt WiFi chip is not natively supported by FreeBSD, so you will need to (temporarily) use a USB WiFi or Ethernet dongle, or (as I will explain) copy some files from a different system to the Macbook. You could also just transplant a different chip into the system."
You say "works perfectly". I do not think it means what you think it means.
To be fair, Linux also has trouble with the Broadcom chip, the driver needs to be installed as a separate step on most distros.

i.e. Declare its working quality after the install is done. The install may take multiple steps. (In this case, copying some files over, apparently.)
Broadcom (and to a lesser extent, Realtek) devices had always been anywhere between hit-or-miss and completely unworkable on Linux, LONG before Raspberry Pi came around.
It's MIT licensed now, which isn't particularly useful when it comes to Pi (there's some Broadcom crap in that boot loader so it won't be open sourced) but otherwise is kind of interesting.
I always saw Broadcom as evil, and saw Raspberry Pi as just reusing cheap parts from set top boxes or similar, with all the proprietary stuff that that comes with.
By that logic, every piece of software ever made can be said to work perfectly in every situation, because there is always some amount of additional work which could be done to make up for its native deficiencies.
That's quite the leap. The work is already done, they just can't/won't ship the driver in base, right? Isn't it comparable to installing Debian and needing to load in non-free drivers separately?
