CEP Advisory Board Member Senator Joseph I. Lieberman writes: "With each new terror attack or mass murder linked to extremist content online, major tech companies like YouTube, Facebook and Twitter make promises to better police their platforms. But after the outrage subsides, very little of consequence changes. It is clear now that tech firms will not effectively and consistently enforce their terms of service, since doing so negatively impacts their bottom line. Patience for their bait and switch tactics is wearing thin, and it is time for Congress to hold this unregulated industry accountable by modifying the blanket legal protection afforded through Section 230 of the Communications Decency Act."
