Actually, the parent question was "what would you describe IBM's motivation for creating *Apache* OpenOffice"..." which was what I addressed.
Remember, just because you can grammatically form a question does not mean the question is logical or that it has an answer. For example, I could demand to know why the town of Gary, Indiana, did not vote for a particular candidate for town council in a 5 person race. The question is grammatical, but does it make sense? It errs in the reification of the town, as if it was a unitary mind with a single preference and a single choice. It also errs in thinking that the vote was against a particular candidate rather than a voting process in which one candidate had the greatest support, and the others, by logical necessity, lost.
The decision to support OpenOffice at Apache was not made by a single person and it was not a decision between only two alternatives. So it is incorrect to say that anyone made a decision not to go with LibreOffice other than by the logical necessity that making any choice eliminates the alternatives not chosen.
