Kim Dotcom, the founder of controversial file-sharing site Megaupload, has vowed that he will beat the ‘political’ piracy case that saw his arrest in January.

US authorities are attempting to extradite Dotcom from New Zealand on the grounds of racketeering and other federal charges. They allege that he and colleagues at his file-sharing website cost songwriters and moviemakers around half a billion dollars in lost copyright revenue by facilitating millions of illegal downloads, while making a fortune for themselves.

Since his arrest on January 20th in New Zealand, Dotcom was granted bail last week under the conditions that he doesn’t leave his Auckland home and isn’t allowed internet access. In an interview published by the The New Zealand Herald, he said that the US authorities were selective in their evidence, cherry-picking emails and other evidence in a “misleading and malicious” way.

In the interview Dotcom said that there were staff at Megaupload who were specifically designated to take down any material that might infringe copyright, however the US indictment alleges that Dotcom and Megaupload routinely took down links to offending material, but still left the copyrighted material in place.

Speaking to file-sharing news website TorrentFreak, Dotcom said “We’re going for this and we’re confident we’re going to win… We feel that the action taken against us was political.”
