Speculation (assuming this is new policy at all):

• They're afraid they're going to get taken out themselves, so they're trying to cause as much damage on the way out as possible.
• They're taking damage to the point that it's becoming harder to carry out operations in a coordinated way, so they're trying to decentralize more so.

Could be wishful thinking on my part that it's a sign of desperation, but if this is out of the ordinary as policy, it's gotta be for some reason and I don't think it would be driven by confidence in capability to control outcomes.
