I went down the rabbit hole on this one a little. They're sending a SHA256 hash of the user's mac address with every telemetry event (which can be trivially reversed. I leave it to the reader to decide whether MAC addresses are personal identifiers). And also for what it's worth, it appears that they are using this ID to correlate what users are doing across their products - as indicated by this comment: "// The hashed mac address needs to be the same hashed value as produced by the other distinct sources given the same input.
