The first one was Wired- not Vox- and the second one was claiming in the prior paragraph that "The platforms are immune from such suits under [CDA 230]. The law treats them as a neutral pass-through" which it doesn't. The law specifically says that platforms can moderate any content it deems objectionable.

Where does the CDA make a platform/publisher distinction? What is the definition of the difference, and where is it in the law?

As Techdirt says, "This "publisher" v. "platform" concept is a totally artificial distinction that has no basis in the law.". Are they wrong?
