Yes, they can. Ordering by time is still a "feed" - a simple one, but it's a feed nonetheless. Many modern phones surface messages from frequent contacts up to the top, above more recent messages from low-frequency contacts. That's also a "feed". Furthermore, most of the calls to violence were made over Facebook messenger which is arguably a lot more like SMS and IRC. I find the argument that Facebook's feed was significant to hold little water. People will coordinate with whatever communication mechanisms they have access to. In the past this was SMS, and even further into the past this was radio. Do we forget the Balkans, Rwanda, and plenty of other atrocities that predate widespread adoption of social media.
