Sorry about the country, county and area pages. They do look bad and they are on the todo list. I figured pub pages were a priority then I just haven't got around to replacing Google elsewhere.
Basically anywhere you see that message it probably means that they haven't given Google their credit card details for map usage - when they realise how much it might cost they probably wont either.
An interesting example is WhatPub, whoever is handling things there has done a great job and set up a quota to avoid getting a surprise crazy bill (something Google make quite hard to do). They have already gone over their quota for the month though and now have the same message.
As I said before, expect a lot of sites to switch to Open Street Maps in the near future.
