The type of open source development is generally unrestricted; the only exception is a product that contains or is an API or a service of which most of the functionality is provided by the SOFTWARE. The derived product must not offer features that are similar to that of the SOFTWARE. This means, this license does not allow developing a product that contains or is a wrapper around the SOFTWARE.
