Software that collects and sends back any form of information is a big no-no unless it's opt-in. It's not acceptable when vscode does it. It's not acceptable when .net-core does it. It isn't acceptable when Luna does it.
If you want your users to help you learn how Luna is used and preforms in real environments, you ask for them for feedback rather than forcefully extract it.
Having telemetry enabled by default (or much worse, being mandatory) is disrespectful. It's also a fairly good indicator of what you think of your users.
