Microsoft Employee Offered Incentives for OOXML Support
An employee at Microsoft’s Swedish subsidiary offered to pay partners to vote to approve the Office Open XML document format as an ISO standard, the company admitted Wednesday.
Microsoft Corp. admitted Wednesday that an employee at its Swedish subsidiary offered monetary compensation to partners for voting in favor of the Office Open XML document format’s approval as an ISO standard.
Microsoft said the offer, when discovered, was quickly retracted and that its Sweden managers voluntarily notified the SIS, the national standards body.
The vast majority of the companies that joined SIS at the last moment to vote in favor of Open XML, according to that report, are Microsoft certified partners.
Besides Sweden, there are unconfirmed reports of last-minute appearances by Microsoft allies to vote in favor of Open XML in countries such as Norway, Colombia, Switzerland and Portugal.
