Broadcom Releases Source Code For Drivers
I'm Not There (1956) writes "Broadcom, the world's largest manufacturer of Wi-Fi transceivers, open sources its Linux device drivers. This is a big win for Linux users, as there are a lot of users that face Wi-Fi problems when they use Linux on their laptops. With these device drivers now open source, distributions can ship them out-of-the-box, and that means no Linux Wi-Fi problems for new devices and upcoming distributions at all."
Congratulations Broadcom, you have just made at least one geek very happy.
While you're at it, any chance of releasing the source for your video decoders? I promise that you will own the HTPC market if you do.

No one is saying that device drives will magically start working flawlessly because their source code is open, although it will make it easier to track down bugs (see Linus Torvalds' quote about the number of eyeballs).
The main point, however, is that now Linux distributions can ship these drives out of the box, so wireless devices will work straight away. Until now the biggest (and dare I say only?) problem I've had with installing Linux on a laptop is finding and installing the right drivers for wireless network cards.
Looking forward to much broader DD-WRT support for Broadcom hardware in the near future
My company manufactures devices for PCs. We do NOT open source our drivers; I'll give you my two cents as to why:
1. Licensing. Our drivers include licensed code from at least two other companies - code that implements algorithms seen as proprietary and valuable by those companies. We don't have the right to publish that code, and couldn't conceivably convince them to do so.
2. Competitive advantage. We have several competitors in our market. The specs that Marketing puts on our datasheets might be optimistic in some scenarios. If we open-sourced our drivers, our competitors could easily demonstrate that to potential customers - if their drivers were closed, we would not have the equivalent opportunity to prove that their liars were worse than our liars.
3. Support. If we publish source, we will end up fielding all kinds of questions from all kinds of people about all kinds of aspects of our product. Even if we simply answer "Go away" to all those queries, there's a lot of time spent reading and replying (or simply ignoring) them. Considering that we sell our products to OEMs for a few dollars, there just isn't any margin for end user support.
4. Security. Say what you will about "security through obscurity", it still has a huge following in the corporate world. Publishing all your source code provides all kinds of opportunities for the scoundrels of the world to take advantage, from the PHB point of view.
5. Financial. There is no business case to be made to disclose this proprietary information. If I'm not going to make money from something, why should I spend the time/effort to open source it, and perhaps give away information that my competitor could use?
In Broadcom's case, there are probably others also - for example, publishing source for a Wireless card could allow operating the RF section beyond regulatory limits - transmitting/receiving out of band, transmitting with too much power, etc. This could jeopardize certification (such as FCC certification in the US) or subject the company to unwanted regulatory scrutiny.
Does this help?

hmm .. I still have to see a driver for any wireless card that crashes linux. Worst case scenario, it just doesn't work, which was incidentally the problem I had with my broadcom adapter on an Acer Aspire One D250. but crash the OS? not really, no.

1. I should spend a month or two of engineering time to write specifications for a block that isn't part of my core competency?
2. Don't take "liar" literally. Marketing is always guilty of Puffery, and in the US this is acceptable. Datasheets always have specifications which, if taken out of context or tested outside the conditions in the tiny print, can be proven wrong. In the market, to remain a viable business, you have to "puff" as much as your competitors do - look at beer, cigarette, car, computer advertising. A company that lets the Engineering department write the marketing materials doesn't survive long. Frankly, our materials are a whole lot closer to reality than our competitors - we've never published wholesale lies, to the best of my knowledge, which isn't always true of those I've competed against.
3. Yes, really.
4. Yes, I know that's bullshit. Tell that to my CEO and CFO.
5. OK, we'll lose your business - that's $3 worth of revenue that we won't receive, once. We hope that you'll see the value of our products in the future and be willing to consider us then.
