It sounds like they were modifying the headline to be more pro Palestinian and more in line with the facts, and edit out some things Israel was saying which turned out to be lies. I fail to see how that matches up with the thesis that Reuters is slanting the story for Israel, or that their headline was getting more pro-Israeli over time, or the broader argument that Reuters is slanting its coverage to manufacture consent (e.g. look at their current front page).

I do recognize that both of those scenarios involve Reuters changing the headline, yes. You don’t have to keep explaining that concept to me; I can grasp it. I was asking OP about some of the details of when they saw these intermediate headlines that they were using to paint a picture that seemed to me to be backwards from the reality.
