If it was law, everyone, not just Cisco, would negotiate cross-licensing deals as such. As a result, there would be no way for people to license IP unless they allowed for open use after the fact.

Beyond that, as an example, open apis (for drivers re:hardwwre) are not the same as giving full chip scematics.

But! If the, for example, SoC stopped updating binary blobs, and things stopped working with newer kernels, as an example, then they'd have to 100% open up and provide sources.

People get all rah-rah about the environment, but I throw away pounds and pounds of highly polluting electronics, just so someone can sell me another.

This model need to stop.

If we required it as a matter of law I hope that my property interest in the actual hardware combined with a statute outweighs those licensing deals.
