Yeah, that's how many companies with open ecosystems work. If you're using e.g. RedHat, you are getting packages with embargoed fixes baked into them before those fixes hit public repos. Node.js, OpenSSL, Git itself all do this.
You can argue about whether the "publicly announced existed" part since they don't advertise for any single package, but that's the ecosystem you buy into.
