"As major tech companies step up efforts to curb extremist content on their platforms, far-right white extremists continue to find ways to spread violent messages and attract sympathizers on the internet. Josh Lipowsky, a senior researcher with the New York-based Counter Extremism Project, told VOA that more pressure is also needed on fringe sites to make sure they meet their responsibility of thwarting supremacist propaganda on their platforms. Lipowsky said 'restricting this type of rhetoric is not limiting freedom of speech under the First Amendment. We are talking about private businesses that provide services. They are well within their rights to set limits on how their services are used to avoid abuse of their platforms.' He added that governments should step in to address these issues to 'ensure across-the-board compliance in the interest of public safety and security.'"
