That's the only (but massive) downfall of Open Play : it is the most toxic environment a Multiplayer game could possibly have. And all that is fully intentional (factual Design Decision).
And in such an environment, no Community or Cooperation can never exist - as it's entirely based on mistrust and betrayal around every corner.
Sorry, but that is a) extremely exaggerated and b) quite misleading. And by slightly misleading I mean: I have yet to actually meet a hostile player. And though I live on the fringe, I have participated in two community events and done a lot of rares trading in the Lave area, with one single attempted interdiction (cut short by my hyperspace countdown.) One.
Yes, there are - as everywhere - outliers, but the enormous effort one has to put in a combat capable ship and the vast space alone keep a lot of potential candidates for that away. Most psychos aren't very patient, and the million credit price tags are the best safeguards we players have against them.
I have, on the other hand, met explorers and exchanged tips about the directions we should take, said "hi" a lot of times, sometimes answered, sometimes not, and cooperated with other players in my part of the fringe. Look at the community goals, the Lugh situation - self-organisation and emergent cooperative gameplay is actually a very dominant part of the game, and I rather suspect it to grow with Wings.
If you want to see a real toxic environment, come to Chernarus.
