Facebook's Monopoly Problem

US federal regulators and dozens of state prosecutors are suing Facebook accusing it of illegal actions in buying up rivals and stifling competition. It's one of the biggest antitrusts in US history and is one of several cases being taken against big tech companies. David Aaronovitch explores the case against Facebook and the evolution of antitrust law in the US. What is the basis on which these companies are being held to account, and is this law an outdated tool in confronting tech titans?
