Say Section 230 is repealed, then its a virtually an internet kill switch. There's trillion dollar companies like Facebook, Twitter, Google, Instagram, Amazon that would be affected. There's no way in hell they'd allow it. They want to control speech, not cut it off all together. The CEO's would shoot Trump themselves before allowing a repeal of Section 230 to go through. It's the whole reason they can look smugly at Ted Cruz during the senate hearings and go "We are a good company with strong moral values"
