Good point, I've missed that. For a fair comparison with rustc or other OSs you should probably either vendor sources for the other code bases too too (e.g. for rustc take the official source tarballs), or delete the third_party/rust_crates directory in fuchsia. I did the latter and got 1.68 million lines of Rust in Fuchsia. Still quite impressive.
