Which brands of wireless cards offer open source drivers for them?

I ASSUME Intel and Atheros do, while the others do not (Broadcom, Realtek, etc). Can anybody confirm this?
I know they don’t need to be open source for them to work, but I’m pretty sure Broadcom is closed source and not only that, they’re very piss poor quality. I’m sure if they were open source, community developers would jump on the code to improve on them. I’m just curious which companies ARE open source because I want to support them by buying their products instead of closed source companies.
