Nice. What about the default telemetry?
The default telemetry is: - (still) not sent until we notify you that it's opt-out - moved (this year) from Google Analytics to our InfluxDB instance (destroying all existing GA data) - only kept for 365 days - contains no PII - no longer even attempts to identify individual users - necessary to be opt-in in order for us to be able to effectively run the project
"But we notified you!"
Consent does not work that way.
It keeps being pointed out that this is a nonprofit run by volunteers - this simply underscores your utter lack of a legitimate business use case for spying on your users.
The only reason people insist on opt-out (ie nonconsensual) telemetry is because they know they don't actually have consent and their ingest data would drop like a rock if they had to, you know, check with their users for consent before uploading their usage. It's the old "she never said stop!" dodge.
Consent matters.
