My sources in Saudi media tell me: this has nothing to do with corruption. Big media moguls are being pressured to surrender ownership to Muhammad bin Salman, who has been pressuring them for months to sell him their media. Al-Walid Ibrahim surrendered a big bulk of his ownership of MBC empire. Sources say that Al-Walid may have been released in return for surrendering control of properties and estates. There is also a petty element: Saudi regime wants to oust singer Ahlam from the program "The Voice" because she didnot support that Saudi-orchestrted song against Qatar.
