Ques 22. Why does the Zend Framework project have a CLA at all?
Ans. The CLA protects all users including individuals, small and medium businesses, and large corporations. By having a CLA in place, we mitigate the risk that companies who claim intellectual property infringement may demand royalties or fees from users of Zend Framework, whether individuals or companies. This is especially important for companies basing their business or products on Zend Framework. The Zend Framework CLA helps to ensure that code and other IP in Zend Framework remains free.

Ques 23. Should I sign an individual CLA or a corporate CLA?
Ans. If you are contributing code as an individual- and not as part of your job at a company- you should sign the individual CLA. If you are contributing code as part of your responsibilities as an employee at a company, you should submit a corporate CLA with the names of all co-workers that you foresee contributing to the project.
