Kyle Sandilands has quit Australian Idol after online activist group the Mad F**king Witches attacked potential advertisers of the Channel Seven show.The feminist group targeted Sandilands’ corporate sponsors for years while he was on KIIS FM, accusing his show of ‘violent misogyny’, crude remarks and offensive on–air content. They claim their campaign prompted 1,900 advertisers to agree not to fund The Kyle and Jackie O Show when it was on air and led media regulators to take an interest in ARN. Sandilands told The Sydney Morning Herald on Friday that he decided to step down from Idol to prevent more damage to the program.‘I spoke with Channel Seven this morning, and those activists have attacked the potential clients for Australian Idol or the clients from last year, and this has caused a problem in Channel Seven’s sales team,’ he said.‘So I’ve told Channel Seven this morning, just prior to speaking to you, that I’m standing down from Idol for the good of the brand to continue.’ Kyle Sandilands (left) has quit Australian Idol after online activist group the Mad F**king Witches, who have held a campaign against the shock jock for years, attacked potential advertisers of the Channel Seven show (Pictured alongside Marcia Hines and Shark)It comes as Sandilands is set to launch his upcoming streaming show, Kyle Sandilands Live, which is due to be released on August 10.The radio star also recently launched a docuseries, At Home With Kyle, which follows the aftermath of his KIIS FM show being axed following an explosive on–air clash with his former co–host, Jackie ‘O’ Henderson, over her ‘fixation’ on astrology.He settled his legal dispute, taking home $12.09million of the original $85million he sought.
