What do you mean by open source license?

Is the CC0 license in the public domain?
The Free Software Foundation and the Open Knowledge Foundation approved CC0 as a recommended license to dedicate content to the public domain. The FSF and the Open Source Initiative, however, do not recommend the usage of this license for software due to inclusion of a clause expressly stating it does not grant patent licenses.
Why is the public domain not a license?
Around 2004, lawyer Lawrence Rosen argued in the essay “Why the public domain isn’t a license” software could not truly be waived into the public domain and can’t therefore be interpreted as very permissive open-source license, a position which faced opposition by Daniel J. Bernstein and others.
Is the Creative Commons license in the public domain?
In 2009, Creative Commons released CC0, which was created for compatibility with jurisdictions where dedicating to public domain is problematic, such as continental Europe. This is achieved by a public-domain waiver statement and a fall-back all- permissive license, for cases where the waiver is not valid.
