This is what I was thinking too. There's really nothing about Git LFS that should come as a surprise. Yes it rewrites history, but how else are you going to cut bloat from the repo after it's been stuffed in there? And the fact that the file is stored on something completely outside of git is clearly and concisely explained as the main text, directly above the download button, on https://git-lfs.github.com/

> Git Large File Storage (LFS) replaces large files such as audio samples, videos, datasets, and graphics with text pointers inside Git, while storing the file contents on a remote server like GitHub.com or GitHub Enterprise.
