Currently, I block pretty much all devices from communicating back with the corporate overlords (at least for stats data).

-- When you need to update your firmware or add/remove activites or devices, you'll need to either disable this rule or disable pi-hole whilst you are working.
Sonos: Add a block rule for msmetrics.ws.sonos.com (or use a Gravity list).
I have 7 Gravity lists going right now that blocks 95% of all ads on the internet and telemetry from various devices:
These are explicit blocks (the amazon.com one is needed to block telemetry from going back to Amazon for Alexa devices.
