SANTA CLARA (BLOOMBERG) - Apple co-founder Steve Wozniak lost his lawsuit against YouTube over videos that used his image to promote a bogus bitcoin giveaway.

YouTube and its parent, Google, are protected by federal law that shields Internet platforms from responsibility for content posted by users, a California state judge said in a tentative ruling Wednesday (June 2).

Mr Wozniak argued in his lawsuit that Section 230 of the Communications Decency Act should not apply because YouTube not only failed to remove the fraudulent videos, but "materially contributed" to the scam by selling targeted ads driving traffic to the videos and falsely verifying the YouTube channels that carried the videos.

Santa Clara County Superior Court Judge Sunil R. Kulkarnia said those factors were not enough to overcome the immunity provided by Section 230. The judge gave Mr Wozniak 30 days to try to revise his complaint.

The scam videos touted Mr Wozniak as the host of a live giveaway, with the promise that anyone who sent in bitcoins would get double the number back. The scheme also used the names and images of other tech celebrities, including Microsoft co-founder Bill Gates and Tesla chief executive officer Elon Musk, according to the suit.

The case is Wozniak v. YouTube LLC, 20CV370338, California Superior Court, Santa Clara (San Jose).
