said by intok:Forced obsolesce? Hmmm - I seem to remember .docx viewers for Word that anyone could download. Plus - Word has always allowed previous formats - if it was true obsolesce then the older version would not be supported at all - only the new one would be supported.
True, but This is Microsoft Office we're talking about. Each new version adds little of value over even long EOL'd versions yet sell by the billions as people are forced to via planned obsolesce from the breakage of file format and lack of security updates.
