It's all speculation, but there seems to be a group think building that has settled on the theory that the one ahead was slow to vacate, and then pointing the finger at how blame can be apportioned.
More speculation, but if the one ahead reported a bird strike, or even the possibility of a bird strike, then unless there is a compelling safety reason to allow the following aircraft to land then I would be required to send it around.
No fuss. No drama. Nobody to blame. Everyone just doing their jobs.
