It's true that all publishing decisions are ultimately editorial, but there's a big difference between deciding to report on what IDF and Hamas representatives say while not reporting on social media opinion, and reporting speculation and interpretation of events.
I don't feel like they failed to contextualize the headline. It was a subpar headline updated for clarity shortly after publication.
There just seems to be a lot of jumping on one of the more factual and objective news sources for a headline taken out of context for failing to include sufficient context.
