What they're missing is that by speaking (and acting) as moral arbitrars, they're stepping into a position they may not want to be long term. If Facebook and/or Twitter are people's primary source of information and they're moderating content that is annoying (but not illegal), do those actions start to fall under FEC rules?

We may see a situation where they have to open up processes, procedures, and potentially algorithms. And I suspect they don't want that.
