Telemetry and Suggest are two completely separate things.

• telemetry goes to: https://incoming.telemetry.mozilla.org/submit
• URL bar “keylogging” goes to: https://merino.services.mozilla.com/api/v1/suggest

The only different between “online” and “offline” is that in “offline” mode what you type in your URL bar is not included in the telemetry sent after you have selected a suggestion. But this changes absolutely nothing to what is sent to the Suggest API endpoint when you type in your URL bar.

I’ve repeatedly provided clear evidence of what I said, you just keep mentioning a random code comment and interpreting it in a way which completely contradicts the actual code and what countless people have observed. So at the risk of repeating myself:

• A code comment does not prove anything.
• Your completely wrong interpretation of it even less so.
• Link to code supporting your claims or GTFO.
