As you stopped reading at that point, I assume the "big claim to make without quantitative evidence" is the part of the article you quoted.

I'd entertain some debate over the definition of publish, as well as whether or not Facebook refuses to accept any responsibility... but outside that nuance it's a fairly objective claim of Facebook's capability and behavior.

I see it as a quite reasonable position to assume that playing violent video games can ease people's inhibition to engage in IRL violence. I personally believe the liberty infringement, and ultimately, violence, that is necessary to ban them is worse than the violent behavior they can influence.
