"Linux is a natural for embedded systems. That's why it's
popping up in more cell phones, often without the customer even
realizing it's there. But cell phone manufacturers, and the broader
sector of embedded systems, must cope with the problem of how to
combine the GPL Linux kernel, and software that isn't Open Source.
How does one do that legally?
"Most of the publicity over suits to enforce the GPL concerns
embedded systems: set-top boxes, cable modems, the list goes on.
The suits are caused by just one thing: engineers and their
managers combining software from different sources, without going
to their company's own lawyers for help in understanding the
software licenses. They're used to just "clicking yes" with no
regard to what they're committing themselves and their company
"The very worst offenders sell their designs to other, much
larger, companies without conveying what the licenses are and what
obligations the big company must fulfill -- and then the big
company gets sued. This problem isn't specific to Open Source:
violation of proprietary software licenses, with their higher
stakes, is rife in the embedded systems industry."
