Is Matt Mullenweg defending WordPress or sabotaging it?

The Google doc linked in this post is theoretically a way for a corporation to harvest the Google usernames of people accessing it. They probably wouldn’t be able to see IPs but that doesn’t prohibit Google from writing your username into their audit logs for them. Use appropriate precautions when accessing.

That's not how it works... at all. Only within an org can you track, and when you share publicly (not individually) you cannot see their view history, only aggregate and anonymous.
