That definition, and Richard Stallman himself, completely agree with me. A BSD license also guarantees "that the users have the freedom to run, copy, distribute, study, change and improve the software".

Here is Stallman spelling it out explicitly:

https://www.gnu.org/licenses/bsd.en.html

> The two major categories of free software license are copyleft and non-copyleft. Copyleft licenses such as the GNU GPL insist that modified versions of the program must be free software as well. Non-copyleft licenses do not insist on this. We recommend copyleft, because it protects freedom for all users, but non-copylefted software can still be free software, and useful to the free software community.

> There are many variants of simple non-copyleft free software licenses, such as the Expat license, FreeBSD license, X10 license, the X11 license, and the two BSD (Berkeley Software Distribution) licenses.

So, I stand by my assertion. You are completely wrong in saying that only copy left licenses are free/libre software, even according to Richard Stallman himself.

The BSD license does not offer the same software freedom guarantees as copyleft licenses though, since downstreams can elect to not release the source code. You are right otherwise though.
