The Foundation sees this as a contradiction to the EU’s own interoperability goals. Although XLSX is standardized as OOXML according to ISO/IEC 29500, Microsoft’s implementations often deviate from the specifications. Furthermore, features often change undocumented, which complicates compatibility with open-source software such as LibreOffice.
So, a bribe with the proper bureaucratic steps?
I think saying that they “bribed the standards body” suggests the body was in on it. The actual allegation (I don’t know any facts, just these comments) seems to be that the body was subverted by other countries that were bribed by Microsoft. Being someone who doesn’t know the details there’s a worthwhile distinction there. Though that still opens questions about the board’s reaction, and I might read up on it all later.
Let me assure you that the original board that was voting for Open Office’s proposal was absolutely pissed off, short of dissolving but eventually unable to revert the decision because of it’s formal correctness.
