On the one hand, it feels wrong to demand Facebook regulate content sent via it just because they profit; you could say the same about telecoms being “dumb pipes.”

On the other hand, Facebook clearly does not want to be just infrastructure; they try to maximize page views and time spent on the site and profit in a much more direct way from popular but horrible content than do ISPs. And they selectively promote content of their own, unlike ISPs (at least until recently!).

In the end I think it comes down to this: if you want to have control, you need to accept responsibility. If you are OK with relinquishing all control, we can negotiate.
