UK Forces Microsoft To Adopt Open Document Standards
First time accepted submitter Barsteward writes Microsoft has confirmed it will start supporting the Open Documents Format (ODF) in the next update to Office 365, following a lengthy battle against the UK government. In 2014, Microsoft went against the government's request to support ODF, claiming its own XML format was more heavily adopted. The UK government refutes the claim, stating that ODF allows users to not be boxed into one ecosystem.
10% effort into actually implementing this, and
90% effort into examination how to creatively misunderstand OPF, extend ODF with "open" binary extensions, denigrate users of ODF, or just plain break ODF
Or maybe it's 1% vs 99%, I don't know.
