This is missing the point though. Let's focus on #1 from above; most people who post things online probably want Google to index them and even do SEO tricks to get there. I post stuff about myself on my website because I want people to see it.

The issue comes when I put stuff on my website about someone else, as in your example. I want my content to be on Google, but you want my content off of Google. At that point, there's a conflict and it's not clear to me who should be resolving it and what position Google should take.

The options are:

1. No one gets to be indexed, which will hurt the millions who want people to discover their content

2. Google has to manually decide in every single instance like the one you mention in your post, that seems unrealistic

3. The status quo, which is that Google indexes what's posted publicly.
