I remember reading an early criticism of the spreadsheet side of OOXML, where a simple spreadsheet with three cells was created: A1 containing '1', B1 containing '2', and C1 containing the formula A1+B1. That spreadsheet was saved, the file opened in an editor which showed the values of the cells, and A1 changed to something else, say 3. This broke the spreadsheet, as there were all sorts of knock-on effects contained in the virtually opaque mess that followed the cell contents.

I've probably got the details wrong, but that was the gist of it. I'd love to rediscover the analysis, but my searches have not yielded it.

exactly, the author ignored the specs and try to come with conclusions of a system, just by doing a Hello World

I think the point of the criticism I read was that the edit should have worked. There is no reason why the opaque mess following what was obviously a definition of the contents of the spreadsheet should even be there let alone be dependent on the original contents of the cells.
