That argument is orthogonal to whether Lua should or should not be spelled in all-caps. Besides being a Portuguese word, it's also the name for a programming language, and that use could have a different spelling rule.
It's not an argument, it's a statement of fact. I'm not more than a Lua dilettante, yet I know this. The name derives from a Portugese word, so it should be treated as a proper noun, not an acronym.
EDIT: iPad completion snafu.
EDIT: For example a "gnu" is an english world (an animal of the antelope family), but we spell the organization that bears a gnu as it's logo: GNU.
GNU is an acronym, which is why it's spelled that way, which is stated on their websites.
