> In fact, although the proposal associates MS Office document formats with the “industry standard” concept, it should be clear that all MS Office documents are proprietary and obfuscated, and therefore inappropriate for interoperability.
Sorry, but this is utter BS. MS Office is a de facto standard, and LO is not compatible with it - it can't correctly open more complex MS Office documents. I should know, since I periodically evaluate it. So the reality is, that MS Office ensures much greater interoperability as LO. Or maybe I am just missing something and we are talking only about server solutions? For example - mayor secretary receives a document from some government agency, in docx format, and LO can't correctly open it. Now what is the fallback solution?
