I disagree that CSR serves the same purpose as code.google.com, and is likely to meet a similar end.

code.google.com hosted public repos, issues, wiki, downloads, etc., and was generally just ripe for abuse. Google created it largely because Sourceforge was the only thing that existed at the time, and it wasn't doing a great job. Today there's GitHub, Bitbucket, Gitlab, and more.

CSR is primarily for hosting private code, shared among teams, and adding integrations with other Cloud services, in the Cloud Console. It also adds code search, which is pretty great. Hosting private repos, it's much less easily abused (it's not impossible). There are plenty of private repo hosts, and this one aims to be the one best integrated with GCP. It has, I think, a much better business reason to continue existing. It might not make money (I legitimately do not know) but it helps drive GCP adoption/usage, unlike code.google.com which didn't.

Disclosure: I worked on code.google.com, and helped turn it down, and helped create CSR from its ashes. I don't work on either anymore.
