1. Org hosts physical web server at www.example.org.
2. Google directs user to www.example.org.
3. User sees url as example.org and notes it down.
4. User needs to visit example.org again, but for some reason it doesn't work.
5. User goes to coworker who shows him that example.org does in fact work (hidden www).
6. Endless confusion ensues.
This is bad UX decision on Google part (on top of it breaking published standards)
