I agree - I'd cite the example of the UK magazine Private Eye. For instance, they've run several articles recently criticising the proposed expansion of London Heathrow airport, despite every issue of late featuring a full-page ad propagandising in favour of it. The lobbyists are no doubt paying a pretty penny for that ad campaign, but there's no sign that's affected the Eye's independence at all. And that's just one example - they've reliably shown themselves happy to bite the hand that feeds.
