I think the primary reason for this (graphics/wireless support, or lack thereof) with regard to FreeBSD is that a large number of the developers -- possibly even a majority, if what I've seen at conferences is any indicator -- don't run FreeBSD as their desktop OS. Instead, they seem to overwhelmingly run macOS. A larger percentage of OpenBSD developers do seem to run OpenBSD on their laptops, however. FWIW, I do recall hearing about some fairly extensive progress being made recently WRT both graphics and wireless support on both of the BSDs recently, so expect the situation to improve quite a bit in the near future if it hasn't already.
