You can have mined materials shipped between outposts, but that’s about all I really know. I only just discovered greenhouses and the way you unlock them is so convoluted. There could be other mechanics that I’m unaware of, but I think you can only ship the raw materials between your outposts.

The longer it continues, the more likely that scenario is IMO. Bitter alt-right extremists would probably start losing interest after a short while, whereas social media competitors would stand to gain from long-term interference.
