Why Don't Companies Release Specs?

Mhrmnhrm asks: "With the recent activism by the OpenBSD crew focusing on release of documentation from the likes of Adaptec, Intel, and others, I'm left to wonder: why do companies insist on believing that by denying access to the specs, they somehow gain an advantage? It's not like telling a programmer how to communicate with the underlying hardware is going to tell them how it (the PCB/silicon) was designed, so why make this information secret?"

Yes. I think so because microsoft DOES threaten hardware companies. It's been proven, in court, that microsoft does this sort of thing.

In short, thinking that MS doesn't use its monopoly to intimidate PC & PC hardware makers is like believeing the world is still flat.

In a lot of ways, yes it is a very small number. First off, I'm not sure which documentation you are discussing from NetCraft. A link would be useful, but I'm too lazy to dig one up. The two stats to remember, are that something like 80% of the domains out there in the world run non-Windows OS's (read people who probably need access to the documentation). I want to say, only 30% of the IP's (possibly physical machines) out there, run non-Window's OS's. So in the end, even on the Internet, Windows is fairly dominate in terms of "numbers of machines". Which is a crying shame in my opinion, but oh well (most hosting companies, use non-Windows machines for deployment).

Now, the number of machines on the acting as servers on the Internet is dwarfed by the number of machines not acting as servers on the Internet. Not a contest. Not even close to a contest. Finally, most hardware vendor's that produce high end hardware do get it. Look at the number of SCSI devices that have documentation or drivers. Not the crappy low end ones, but the really good stuff. Sorry, the crappy low end adaptec IDE RAID cards aren't ever going into a high end server. Most internet servers don't really need a good 3D card from Nvidia or ATI. Look at the e1000? Yep, got a lot of those sold, and some really good documentation available to the public. Now look at the wireless chipsets, never going in a server. Not going to get public release based off domination in the "NetCraft" stats. 90% of all wireless cards will never ever be put in a machine that is counted by "NetCraft". They will be put in machines that say, 90-95% of all shipping computers have a Microsoft OS on them.

So depending on the product, yes, the NetCraft numbers are insigificant, both in terms of percentage and raw numbers.

For other products, the NetCraft numbers make a lot of sense. Look at the number of Open Source drivers for high end SAN cards. Look at the number of Gigabit cards that have open source drivers. Look at the number of highend RAID cards that have open documentation.

The other thing they are confusing is "won't release specs", versus won't allow re-distribution of the firmware. For a lot of wireless cards, it's that they can't re-distribute the firmware which is necessary for the hardware to work, not that they don't have the specs for the actual hardware. (I believe a number of OpenBSD's issues with Wireless Intel chipsets are this issue). The other issue with Wireless is that releasing the specs could invite FCC issues. I'm not sure of how much teeth those could have, but it sounds like a legitimate concern. If the FCC could say, well people are using your part with your documentation to drive it out of complaince, your wireless cards can no longer be sold. That'd be a real problem for Intel or Cisco.

Finally, releasing the specs, would allow a competitor to say they clean room, backward engineered without having to do the documentation. It's really expensive to do that testing and documentation. So they could sell a competing product at a much lower price. It's much easier to match an existing specification, that it is to write a good known working specification. It is valuable IP. Personally, I think it's wonderful when they release it. For a lot of hardware they do. Especially for the really high end hardware that needs high reliability.
