Social media platforms such as Twitter and Facebook have an important role to play in mitigating the effects of Russian messaging, but their primary objective is generating profits, not defending Western political systems. Attempts to introduce legislation or regulations to restrict online speech, even if they were targeted at Russian disinformation and trolls, could mirror Russian constraints on free expression and could be interpreted as running counter to the values Western societies seek to defend. Nevertheless, tech platforms have an interest in taking firm steps to prevent, for example, the hijacking of profiles of legitimate organizations and individuals for the purpose of disinformation. They also have an interest in cooperating with Western intelligence agencies, as this could provide them with greater understanding of how their systems are abused to systematically deceive their users, as well as of software bugs and other technical vulnerabilities in their products.
