I didn't this happened elsewhere. Here in France it's a huge problem, providers even talk about youtube in their ads to get people's attention. Free is the most famous case in France because they constantly refuse to do their jobs thinking that it's google's job to do (I don't know who's right but I left them because of their problem with youtube). Few months ago (or was it a year?) they upgraded their modem to block Google advertisement by default. A pretty bold move.
