As can be seen in the Oracle v Google lawsuit, legacy vendors are getting together to try to overturn a court ruling that APIs are NOT copyrightable. If successful in their appeal, the ruling would prevent competitive implementations of the same API, resulting in a new kind of lock-in that reduces competition and set a precedent that affects all APIs and programming languages.
Our economy will be more competitive when people can switch providers using compatible APIs. Thus it is important to protect the openness of APIs and the freedom of software developers to provide alternative implementations.
Entrenched software vendors are banding together to protect their proprietary interests. We need to show the people's support of the other side. Please support API freedom.
