That said, questions have been asked about AdBlock Plus' controversial whitelisting service, which has been described as a racket. Advertisers whose content isn't obnoxious can apply to be exposed to web users, but one unnamed party claimed that it was asked for 30 percent of its revenue to remain on the list. Naturally, the company's Ben Williams refuted this claim to BBC News, saying that if the accusation was true they'd be "terrible racketeers because 90 percent of the people on the whitelist don't pay anything." Smarting from their courtroom loss, the German newspapers are already gearing up for an appeal, so expect to hear plenty more about the moral quandaries of using ad blocking software in the near future.
