So this is just a very harsh discussion of semantics? Moreover, one where the argument is based on common understanding of a term, rather than a literal interpretation of the term.

Because a literal interpretation of open-source is a system where the 'source'(code) is open (to read). Indeed many people understand it to mean more, but that doesn't make that understanding indisputably correct.

"Open" doesn't mean "read", it means "freedom". If I look up the definition of "open-source" for instance on Wiktionary [1], it says "permit modifications and redistribution" (and refers to the OSI definition).
