> To create Free software, you ship sources together with your binaries and one of the OSI-approved licenses, that is all.

Untrue. Shopping source with _some_ OSI-approved licenses makes the work Free software. Shipping it with others merely makes it open source software.

[MaxBarraclough]

Technically correct, but not an issue in practice. If you want a licence that's approved by the OSI but not the FSF, or vice versa, you have to go looking for it. If memory serves there are no licences in the latter category, and the few in the former category are very obscure.
