Charles Hoskinson, CEO of Input Output Global, has accused Cointelegraph of defamation regarding its coverage of a $600 million ADA voucher controversy. Hoskinson claims that Cointelegraph's editor-in-chief, Jon Rice, has refused to retract a story implicating IOG in the incident. He has called on other crypto projects to withdraw advertisements and avoid Cointelegraph events. An independent audit conducted by McDermott Will & Emery and BDO revealed that 99.7% of ADA vouchers were properly redeemed. The audit also confirmed that unclaimed tokens were allocated for ecosystem grants through Interspect.
