I'm not sure telephone companies or shipping services are a good analogy here, though, yes, that's an example the opinion uses. One key difference is that telephones are generally one to one or one to few communications, whereas social media platforms are a megaphone to speak to many people? Do other forms of mass communication require you deliver any and all speech?

If you're going to say social media is like a telephone, I think you have to at least consider in what ways it actually isn't like a telephone.
