Just on a quick read: two misleading statements already..
"Microsoft said its employees would join an International Organization for Standardization (ISO) and International Electrotechnical Commission (IEC) working group to MAINTAIN Open XML"
Excuse me, it hasn't been formally released in an acceptable format. Until all the corrections are brought in it is AFAIK not maintaining (which suggests some acceptable baseline to start with), it's still "workign towards compliance with our own commitments as required per ISO process, broken by us or not ".
"Microsoft's embrace for ODF comes just two months after Open XML was ratified by the ISO/IEC as a standard."
I think we still have to be careful with words here. "Ratified" here means "voted in after the voting process was subverted to the point of rendering the relevant ISO branch inoperable, an operation of which the true scale of damage yet has to be properly assessed". Let's not forget that MS principally BROKE ISO in its desire to subvert government procurement processes.
Lastly, PDF and ODF beware. Does "Embrace, Extend, Extinguish" ring any bells?
I think it requires a whole lot more than promises and press releases to undo the damage MS has caused to their own reputation. Show me anyone who trusts MS now..
