ODF not an XML-based dump of OOo
The article says "A more even-handed sentence might read: ODF is an XML-based dump of the internal data structures of OpenOffice, while OOXML is an XML-based dump of the internal data structures of Microsoft Office."
It may be evenhanded, but it's inaccurate. ODF is designed as an "idealized" representation of a document. The specification says that ODF "...provides for high-level information suitable for editing documents", and that's not what a dump of OpenOffice.org's internal data structures provide.

Why PNG didn't catch on
The article states "Likewise, the PNG (Portable Network Graphics) format fixed issues with GIF (Graphics Interchange Format), but it hasn't replaced it."
One reason, of course, is that Microsoft never supported the specification completely; transparent PNGs didn't work in Internet Explorer until very recently.
