Zuavra has a detailed and interesting analysis. The conclusion:
There was nothing evil in Romania in regard to OOXML. There was no conspiracy.
The “yes” vote from Romania was a combination of: poor organization from the part of ASRO; making people without the necessary skills or information vote on something they knew nothing about; misunderstanding of the ISO voting procedure; acute lack of interest from the Romanians at large. Therefore the vote passed the way it did as a sort of default.
It can be argued that Microsoft’s propaganda may have had a role to play in this outcome. If it was so, it was one of the few countries where it had so incredibly little resistance to overcome. There’s no evidence that Microsoft Romania did anything to actively influence the vote of any member of Technical Committee 210. They didn’t have to.
With minimal, concerted effort, the result may have been different. One can speculate all they wish about what Microsoft Romania, corrupt individuals or interested companies would have done to counter an anti-OOXML movement in Romania. But there was no such thing and we can only dream of “what if”.
