Unfortunately most Google software is practically inseparable from Google's infrastructure. Open sourcing stuff is hard, mostly thankless work.

Neat things do come of it though. Code Search, for example, ended up as an technical explanation [1], which I found fascinating, and example implementation [2], which I found useful.

That's not actually the codebase for code search though -- it's a re-implementation of it done in the original authors new language.

That's my point though: just because a retired product is heavily tied to Google's infrastructure doesn't mean that they couldn't release something useful out of it.
