Apple co-founder Steve Wozniak has sued YouTube over the proliferation of "bitcoin giveaway" scam videos on the YouTube platform. The videos falsely use the names of Wozniak and other celebrities—including Elon Musk, Bill Gates, and Ethereum founder Vitalik Buterin—to give the scams legitimacy.

Scammers hijack popular YouTube accounts and change their names so that they appear to be the official accounts of celebrities like Wozniak or companies like Apple. They then broadcast a "live" video showing old footage of the celebrity discussing cryptocurrency or related topics. Alongside the footage is text claiming that if someone sends bitcoin to a particular address, the celebrity would send back double the amount.
