1. Because Facebook didn't comply with every request, they never felt coerced and neither did any other social media company, therefore no social media company was coerced.
2. The Democrats who threatened to repeal or modify 230 and the Republicans who threatened to repeal or modify 230 would never repeal or modify 230 because of party politics, therefore this wasn't a realistic threat and therefore not form of coercion.
Does that sum up your argument?
