Responding snark with snark: Then don't use them.

Most wireless cards out there work just fine. When I had to use a laptop with a Broadcom chip for uni I used my Android phone as tethering (charging it as a bonus) and the guy sitting next to me just used a dongle smaller than his thumb.

Most people (even developers) aren't willing to open up their laptop to replace their laptop wifi cards or to have to use dongles to get on their wireless or to play endless hardware roulette.

OSX doesn't work on all windows-only hardware either. You have to buy something with Linux support.

I have linux distros running on 3 of my apple laptops with broadcom cards - it just meant using a nonfree firmware

I even have problems with Intel card from time to time.
