You are certainly entitled to your developer perspective.

What are the reasons users do not read the /legal/data page on the Julia website? What are the reasons users do not read 200+ posts from developers debating the use of opt-out telemetry? To ignore such reasons, assuming they exist, would also be disingenuous.

If you put the choice clearly before users and they knowingly, affirmatively choose to submit usage data, then no 200+ post thread is necessary. Instead, the choice is not left to users. It is made by developers, and the fact of the use of opt-out telemetry is found on a webpage that developers know users do not read.
