The US authorities are campaigning to extradite the internet millionaire from New Zealand to face charges of copyright infringement and racketeering, after shutting down the cloud storage service in January.
Wozniak, who was photographed at Dotcom's home earlier this month, has now spoken out against the legal crusade he is facing and questioned the American government's record on human rights.
He told CNET: "When crimes occur through the mail, you don't shut the post office down. When governments dream up charges of 'racketeering' for a typical IT guy who is just operating a file-sharing service, or accuse him of mail fraud because he said he had removed files [to alleged infringing content] when he'd just removed the links to them, this is evidence of how poorly thought-out the attempt to extradite him is.
"Prosecutors are attempting to take advantage of loopholes. Too bad for the US government that Dotcom lives in New Zealand, which is better on human rights."
Wozniak also criticised the prosecution's failure to provide Dotcom with enough funds from his frozen assets to cover his legal fees.
"How unfair that the United States will allow him living expenses out of his frozen assets but not give him any legal fees. The side with access to the funds spends millions on lawyers hoping the other side goes bankrupt and gives in," he added.
"Shame on the system that permits this one-sided advantage. Kim is well enough liked and respected that his legal team is working without up-front payment."
The Apple executive also claimed that Dotcom did "more than can be imagined" to prevent online piracy by removing links to copyrighted content.
