I am concerned about run-time telemetry in libraries as well. It might make sense for language ecosystems to offer more data about library usage gathered at build time eventually, as a different system than the one I'm posting about today. I think when you get to that level of detail you probably need to start thinking hard about differential privacy and probably cryptographic solutions like ESA or Prio. I don't think we know enough to design the library solution yet.
- JohnFen 4y agoTelemetry embedded in libraries is simply abusive, in my opinion. At the very least, the decision about whether or not to include telemetry should be made by the application developers, not the toolmakers.
- rsc 4y agoRight. My hope would be that language tooling offering library developers visibility into compile-time information about library usage would reduce their desire to insert run-time collection instead.
