Almost official: Murdered Justice League are clones.
In the new audiologs, Dr. Freeze tells Amanda Waller that she compared her data obtained from the studied Flash and Lantern with the analyses that Lex Luthor did on Batman from the main story. As a result, Freeze comes to the conclusion Squad fought with Justice League clones, and now they have two originals who have lost their memory. This is also confirmed by how obedient and cruel the Justice League was from the main story. At same time, Amanda Waller is in no hurry to share data with others, powdering Freeze's brains. Waller has plans to control the Justice League using Brainiac's technology.
