That's what ultimately lets us still do plenty of things for devs and the OSS community:
(1) Our super popular public code search is at https://sourcegraph.com/search, which is the same product customers use internally on their own codebases. We spend millions of dollars annually on this public instance with almost 1M OSS repositories to help out everyone using OSS (and we love when they like it so much they bring it into their company :-).
(2) We also have still have a ton of open-source code, like https://sourcegraph.com/github.com/sourcegraph/cody (our code AI tool).
BTW, if any founders out there are wondering whether they should make their own code open-source or public, happy to chat! Email in profile. I think it could make sense for a lot of companies, but more so for infrastructure products or client tools, not so much for full server-side end-user applications.
