My second language is Spanish, and I understand quite well what 'Libre' means. In my view, there's no real difference between FLOSS and FOSS, since 'Free' translates to 'Libre'. However, when 'Free' pertains solely to 'price', it's more accurate to use 'Gratis', which means 'No Cost'.

Additionally, considering that words can have multiple meanings in English as well, I question the necessity of incorporating an 'L' from another language into an English acronym. Instead of complicating the acronym, I believe in giving a clear explanation.
