It seems to be about wanting to know who you're talking to when providing free support for an open-source project, and whether the person submitting an issue is using the project for personal use or within an organization.

> If I don’t know who you are, am I enabling you to build the new Turkish censorship infrastructure, or helping you implement [Russian internet blocking] more efficiently? These are two examples that actually happened by the way.

If you're afraid of doxxing and / or stalking though, at least you have the choice to not contribute. You can still post somewhere else and ask someone else to make the report for you if need be.
