Complete and utter nonsense.
The win has been postponed, they take their job deadly serious and that includes not blocking mergers unless absolutely necessary....because mergers do still have benefits in areas like GDP, etc that the country benefits from in the short term even when consumers or competition eventually loses.

They need 6 weeks to consult all those that might be affected, and even this extension won't be enough, but as these are by except, they might need to apply again after receiving further feedback, but realistically they don't need 6 weeks to say no, which by the legislation is their foregone conclusion of the remedies offered by Microsoft, as they still are Microsoft with Windows , Xbox and Azure, and would still own Activision's library. It is that simple.
