If you have thousands of contributors, then branch graph becomes incomprehensible. Only linear history will do at that point. Linear history is easier on everybody but the contributor who can't wrap their mind around it. It's easier on everyone else because git log tells them everything they need to know -- no need to chase branches -- and because commits are meaningful (because the contributor must take the time to make them so).
