Again.

Free software is largely coterminous with open source. Even Stallman uses the term 'copylefted software' to refer to software under a so-called copyleft license -- one which, like the GPL, forbids license changes upon redistribution. Stallman will tell you that he'd rather your free software be copylefted, but it doesn't have to be.

You're right about source-available though. It's what we used to call 'shared source', after a failed attempt by Microsoft to promote that as an alternative to the viral, cancer-like open source.
