I do think the pronunciation issue is going to hamper its adoption, though. If it’s pronounced as it is in French, it’s very similar to how we say the zodiac sign “libra,” but if you don’t know it’s french, it could easily be Spanish/Italian/Latin and be pronounced “leebray.”
The fact that it’s not an easy word to know how to pronounce means that people who have only read it will be hesitant to use it in conversation or public speech.
In fact, just learned now that it's supposed to be loaned from French, I had always assumed it to be from Spanish (I'm biased because I'm Spanish).
Is it? According to https://www.gnu.org/philosophy/free-sw.en.html
‘We sometimes call it “libre software,” borrowing the French or Spanish word for “free” as in freedom’
