Yes, true. but: that doesn't matter, at least to the argument in question.

a. Google complains that these companies were colluding against them in the Novell deal. b. Microsoft shows that they were not in fact colluding against them in the Novell deal.

Whether or not it would have made business sense for Google to join that pool (it clearly wouldn't have) doesn't matter within the narrow scope of whether they're entitled to complain using the specific words they've chosen to make their complaint, which, for whatever reason, people seem to really enjoy discussing on the internet this week.
