There was an opt-out telemetry proposal in Go [0], which caused a huge backlash. The proposal authors were so focused on the benefits of the telemetry, that they did their best to invent all kinds of very convincing arguments why their telemetry is okay, useful, not intrusive, etc. etc. They completely ignored the ethics of the problem - that they are not entitled to users' data without consent.
It took a very dramatic reaction from the community to convince them that adding opt-out telemetry without users' explicit consent is a bad idea, no matter how "non-intrusive" and "helpful" it is.
