Destroyed is too strong; it would basically terminate all social media sites, news aggregators, comment sections, forums.. everything since precisely nobody is going to sign up for the legal liability. (Except, maybe, for megacorps like Facebook, with a net gain of nothing)

I would like to see it greatly narrowed.

Even if we ignore this particular instance as a special case where the act was justified, large companies having unfettered control over most political discourse in the country, and wielding that power in an arbitrary, unaccountable way is still a problem.
