Perhaps. It's also possible that this reverses causality and that they use the product name "LibreOffice" because of the existing term "libre software", rather than using "libre software" primarily because that's what the product is called.

After all, "libre software" has been used in English since the 1990s, the EU was writing legislation about libre software in the 2000s, the Free Software Foundation has hosted an annual LibrePlanet conference since 2006, and even gnu.org recommends using terms like "free (libre) software".
