"Format Sovereignty" Can Only be Accomplished With LaTeX or OpenDocument Format (ODF) or Vendor-Neutral Standards for Editable Documents
Two days ago the TDF blasted "OOMXL" as a fake 'standard' (Microsoft bribing officials all around the world to pretend Microsoft Office was an "open standard").
Quoting TDF: "When a public administration is told its documents are stored in “an ISO standard format,” the assumption is reasonable: an ISO standard ought to be a clean, implementable specification that any qualified software vendor can support. Standards exist precisely so that nobody is locked to a single supplier."
Microsoft Office with .docx is no such thing; it's not even "OOMXL", it's just a proprietary format which changes all the time.
This week Macworld (IDG, same network of sites that keeps pushing false advertising for "lifetime" Office because Microsoft pays it to do so) published "Microsoft warns that some Office files might not work on your Mac next month".
As associate has noted this this is "an opportunity in to a deep dive against vendor lock-in through proprietary file formats, plus an opportunity to raise complaints against proprietary software in general."
Thankfully TDF (or LibreOffice) is already doing just that, even if it does not speak of what Microsoft has just done to users of Microsoft Office.
Nobody at Microsoft was ever held accountable for the white-collar crimes associated with OOXML (which not even Microsoft Office supports).
Microsoft is, in effect, above the law. Recall this: Microsoft Crime: A Week Later No Investigation Launched, No Microsoft Executives Prosecuted, Nobody Phoned the Police, Not Even a Slap on the Wrist █
