I have developed a software that uses (is statically linked to) code licensed under BSD 3-clause license. Just reading the license terms, it seems to me that I'm obliged to allow any one who I sell (redistribute) my software to, to have the right to use the whole software under the conditions of BSD 3-clause license. This is because the license has to be incorporated in the distribution.
It seems however that quite many people are convinced that this is not the case and that is possible to apply a more restrictive license to the whole software without violating the original terms of the BSD license (see for ex wikipedia). If this is possible, how can that be? What am I miss-interpreting?
