Payment service provider PayPal cut WikiLeaks’ online donation account Friday.

WikiLeaks violated its acceptable use policy, “which states that our payment service cannot be used for any activities that encourage, promote, facilitate or instruct others to engage in illegal activity,” PayPal said in a statement.

WikiLeaks, which confirmed the change Saturday, said on its Twitter page that the action was based on U.S. pressure.

The tweet sends readers to a donation page, where supporters can pay by credit card, bank transfer or through the mail. The page also solicits for a defense fund for founder Julian Assange.

Assange’s whereabouts have been undisclosed since WikiLeaks began publishing 250,000 confidential U.S. diplomatic cables earlier this week. He is wanted by authorities in Sweden on unrelated allegations of sex crimes, including rape.

Assange has denied the accusations, calling them a smear campaign.

WikiLeaks posted an article on PayPal’s move on its Facebook page. More than 2,400 people, many upset with PayPal’s decision, left comments Saturday.

A U.S.-based domain name provider shut down WikiLeaks early Friday, but the controversial website announced hours later that it had employed a company in Switzerland and was back up. Amazon also kicked the site off its servers.

Last month Skype was in talks to acquire VoIP startup Gizmo5. It was a perfect backup plan in case all that IP litigation didn’t work out. Gizmo5′s SIP infrastructure could theoretically replace Skype’s proprietary P2P back end.

After the Skype settlement, though, Gizmo5′s strategic value to Skype sort of plummeted. In the meantime, Google bought them, say multiple sources with knowledge of the deal, for around $30 million in cash. The deal is done, say our sources, and will be announced shortly.

Gizmo5 is a good fit with a number of Google products. Google Talk allows voice calls between users but has no PSTN link to allow incoming or outbound calls to real phones. Gizmo5 does this well already.

And Google Voice is a great VoIP and phone identity service, but they have no endpoint for calls. Gizmo5, which by the way already integrates with Google Voice, is a soft phone end point for Google phone users. In other words, you will be able to make and receive calls to your Google Voice phone number from your computer.

This looks to me like Gizmo5 will be the glue that puts Google Voice and Google Talk together into a single product. And that product looks a lot like a Skype competitor.

Gizmo5, which was founded in April 2003, has raised $6 million to date, plus an unspecified amount from founder/CEO Michael Robertson. Prior to Gizmo5, Robertson gained notoriety with his founding of MP3.com and later MP3tunes (which has led to big music suing both the company and himself personally).

We’ve reached out to Gizmo5 and Google for comment.
