Given that the original title "Refresh hangs indefinitely, appstreamcli using 100% CPU" wouldn't probably have made the front page, yes, I'd say it has been editorialised for added sensationalism, like "failing all over the world"

For me, that is not accurate. If OP wanted to give a bit more context other than the original title, they could have changed it without adding the sensationalist part, for example, "Ubuntu bug breaks apt-get update" or similar.
