French newspapers are so unhappy with people using adblockers when accessing their sites that they have begun to ban people using the software from accessing their websites, in a move denounced as "hysteria" by one adblocking firm.
The latest measure from leading news sites such as Le Monde and Le Figaro It is the latest battle in the war between publishers desperate to create sustainable revenue streams and adblockers. Advertising is a key source of revenue for online publishers but adblocking has put that under threat.
"The contact with the users is that you can pay, or you should accept advertisement. This is a contract and it's important," Emmanuel Parody, secretary general of Le Geste, the body that represents online publishers who organized the anti-adblock action, told CNBC by phone.
"This is a starting point for a new debate."
