Does it matter if you pronounce it wrong - half the words I use for internet things I'd never heard anyone say until I'd used them for a long time.
"my SQL" vs "my-sequel" (I use the former), NginX I still pronounce as "en-jinx", similarly GIF.
If people call it "lib-ruh" software it doesn't really matter as long as the meaning is conveyed.
It's easier to pronounce if you're a romance speaker, but still not consistent, again due to the location of that "r." "Free" is pretty easy to say for everyone, and recognizable whether your "r" is a flap, is French, or is the English "r" which sounds like a humming engine.
