Fine on the unauthenticated part. But about private data - it's literally anonymous and just counting the number of installs of a package and the number of build failures. All the data they collect (and the code that handles it) is public. They can't even isolate individual users because no individual data is collected.

It includes a persistent unique identifier, generated on install, a sort of Homebrew supercookie for tracking you across months or years until you wipe your OS install.
It also includes the client IP address (because you can't make an HTTP connection without transmitting that). The fact that Homebrew doesn't see this information doesn't mean it's not transmitted (to Google). This leaks your city-level location.
These two things permit Google to assemble a rough location tracklog based on client IP geolocation (correlated via the unique install ID), along with which packages you installed. Google, as we know, spies for the US federal government.
You're missing the point here, though: even if it were totally anonymous (which, as I've pointed out, it's not): it's still unethical malware even in that case because it's private data transmitted without consent. The fact that you don't consider your usage data private is fine; others do and transmitting that from their systems without consent is abuse.
I mentioned that it's unauthenticated to point out that there's literally nothing stopping anyone on the whole internet from polluting the dataset with whatever bogus information they want. I wouldn't undertake this myself, but it's entirely in-bounds for an organization that feels entitled to co-opt your private computer to conduct surveillance on you without your consent. It's a public API, after all.

Please mind that knowing unique installs will remain important for us though. We have zero interest in tracking people but we do need meaningful install counts. Those numbers have been super helpful for making decisions, for example which packages are worth maintainers’ time and which aren’t.
