This whole situation says much more about Ellison and Oracle than it does about the EU. Everyone already knew that the EU Commission marched to a different drum beat than the DOJ. It really doesn't matter whether the commission is right or wrong according to some external measure (i.e. everyone's personal opinion), they have the last word on this merger.
The mergers and acquisition group at Oracle should have known what they needed to give the commission before the deal was even publicly announced and then handed the commission everything they would need to make a rapid decision. That might have included Ellison deciding up front to jettison MySQL immediately after the acquisition. Right now the decision is being held up because Oracle has asked for more time to prepare a response.
