We chose this license, because we believe in free software (free as in free speech) and we think that free software should remain free. We even think this freedom should go so far as to enable commercial vendors to use it and to redistribute it along with their proprietary code.
If for any reason the license is not suited for you or is not compatible with your project, please get in touch with us. We will find a solution.
