The Editorial board consists of application authors, company representatives and interested people. They control the quality and steady pace of development. The mentioned freedom of software and data is a significant advantage for software engineers and users. It is the same principle which works for the Linux operating system. The source code for all packages is available.
Developers can rebuild the product.
It is possible to enchance it and distribute the results afterwards. This is especially important for the data. The only license restriction is that the source code and the product have to remain open even when you improve them. Some packages have licenses which also allow to change these terms. Service and support for these products is still offered.
