Submission + - LibreOffice Once Again Slams Microsoft For Using 'Lock-In' With Office Files (xda-developers.com)
Vignoli explains his point by stating that open document formats don't hide anything. People developing their own apps can use the format to both read and write the document format with perfection. Meanwhile, proprietary formats such as Microsoft's "contain undocumented features, private extensions or behaviours" that developers can't fully adapt to. That means that a presentation that looks great in the source software comes out strange when rebuilt in a third-party app. This, Vignoli says, is a huge issue [...]. Vignoli claims this creates a huge issue with document preservation. If a Word document was saved in one version of Office, will it still be readable in 20 years? Microsoft has added legacy support to its software before, but the company can one day decide that it's not worth the effort anymore and cut it out. When that happens, you have old documents that are either jumbled or unable to be opened at all.
