"Telemetry settings in Kibana" indicates that it is about telemetry settings in Kibana. Which is what the article is.

"telemetry.optIn defaults to true" indicates that some setting, somewhere out in the world, defaults telemetry to true. It's a clickbait title.

Poster should have titled it "Kibana Telemetry Is Opt-out" if they wanted it to be a proper title.

OP's problem is not about telemetry. Their problem was exactly what the title meant, "Opt-in" means user should make it true if they need, instead they have an opt-out with a name opt-in.

Imagine buying wipes labelled wipes, but they were actually dry tissues.

Precisely, thank you.

It’s not about Kibana, or telemetry, or telemetry being opt-out. It’s about exactly what I copied from the page for lack of a deep link: the opt-out setting is deceitfully named opt-in.

It's more than just that it's opt-out - It's that the setting is even named 'opt in', while not being opt in at all.
