You should also factor in their software model. GitLab has a free install anyone can run locally without having to register. A competitor like GitHub has enterprise install but otherwise most public traffic is on their own hosted install. If there's a security issue they likely fix their hosted install and inform their enterprise customers only -- as well they probably shouldn't make it public otherwise it could be considered some level of exposure to their customers. Conversely GitLab essentially needs to publicize this to maintain the trust of their customers.
