This is Open Telemetry functions you're referencing. Being able to trace, profile and debug your own code that's executing in a highly distributed environment is a pretty useful thing. This isn't (necessarily) user behavior telemetry.

At least understand what you're looking at before getting the ick.

Good luck running a server without any sort of telemetry. How will you debug stuff without logs and traces? Seems to me that the priorities are with practical, real everyday engineering concerns.
