It is perhaps the way you've presented the argument that is generating downvotes, but I fail to see how this is outside the realm of Facebook's pursuits given past behaviour and current activity.

Or is it that people would support this use because of a 'noble intention?' (ends justify means)

Would Facebook then start making calls to the police for welfare checks when a user stops using Facebook without closing their account? Surely, something must have happened to the user if they stopped logging in frequently. After all, users don't just stop using the service.
