Dale Clapperton, then chairperson of EFA, argued that the Labor party cannot implement the clean feed proposal without either new legislation and the support of the Australian Senate, or the assistance of the Internet Industry Association. As the Liberals and Greens have both stated that they will not support legislation, it can only be implemented with the support of the IIA. International lobby group Netchoice, which is backed by companies including eBay, Time Warner, Oracle Corporation and some trade associations, is likely to oppose the mandatory filter. Google opposes the filter primarily because the scope of content to be filtered is too wide, and is likely to delay the introduction of Google TV to Australia because of technical concerns about the filter. Internode engineer Mark Newton was the subject of a letter of complaint from Stephen Conroy's office for his participation in a Whirlpool forum showing the negative impact of the filter on Internet access speeds. Some child welfare groups including Save the Children and the National Children's & Youth Law Centre have criticized the filtering plan as ineffective, stating that resources would be better spent elsewhere, and agreeing with the opposing position presented by Australia's ISPs. Other child welfare groups continue to support the filters. In 2008, ChildWise defended the plan as "a victory for common sense". NSW Young Labor has abandoned the web filtering plan, passing a motion rejecting Conroy's plans, and calling on him to adopt a voluntary, opt-in system. Colin Jacobs, vice-chairman of Electronic Frontiers Australia, said that the pitfalls of mandatory ISP filtering were illustrated by the problems in the UK caused by the blocking of a single Wikipedia page. He also said of the IWF blocklist: "In Australia, not only would the Government have the ability to secretly add any site to our blocklist, but an unaccountable foreign-based organisation would as well". Conservative South Australian Liberal Senator Cory Bernardi does not support the mandatory web filter. He considers Stephen Conroy's plan to be "so devoid of detail" that it is impossible to form an opinion on it, and says "Parental responsibility cannot and should not be abrogated to government—if it is, our society will only become weaker ... Yes, illegal content should be banned from the web ... but it is wrong to give the government a blank cheque to determine what is appropriate for us to view on the Internet." Clive Hamilton, a
