YES. Recently many platforms were key in deplatforming ISIS and slowing the rate of radicalization. ISIS was an internet phenomenon and when their media was pushed to less famous outlets then their outreach was weakened.

Ever since the beginning of the Internet webhosting companies have colluded to deplatform the KKK and a few other notorious white supremacist groups. This has been largely successful in curbing the outreach of the KKK in the United States. It's also why YouTube is getting a lot of criticism for embracing white supremacist groups and facilitating thier growing outreach. This is a break from long-running comm business practices.
