They've found Code Jam to be a pain for a long time now, because the results never align with their ideology. Men (mostly eastern European and Asian) dominate these competitions to such an extent that Google created another Code Jam that excludes them, so women had a chance to win prizes. Also, Code Jam is often won by the same people year on year, look at the leader boards for the previous years.
I mean, things like chess have had women-only tournaments for years, that seems acceptable to me.
Still, I think it's pretty sad that "results don't conform to our ideological results" equates to "it must be a bad metric, let's shut it down!" Hope it's not the same kind of thinking that led to ElectronConf being cancelled a couple years ago for "not having a diverse slate of speakers", despite the fact that all proposals where chosen in a blinded process explicitly set up in a way to eliminate bias: https://news.ycombinator.com/item?id=14480868
