The first link seems a bit unrealistic. This is an online community, after all, and we've seen the naysayers try to rip it apart before and it still stands. So while entertaining, probably not reality.
The second point, though. Activision is the current owner and that kind of sucks. BUT, I somehow doubt they're even aware of their IP. Plus, as far as I can tell, their trademarks for the game have expired a long time ago without being renewed so I think it's safe to say that they're uninterested. Their interests appear to lie with the money makers that Sierra produced -- Kings Quest among others. If we were a Kings Quest community I'd be holding my breath but Outpost really didn't bring Sierra much, even Outpost 2 within a few months of being published got dumped down to $15 just to get the manufactured copies out the door and break even on it.
So suffice it to say I'm not terribly worried about Activision. Besides, a CnD doesn't require us to shut down the community so even if we did receive such a notice OPU will still stand as will the many non-infringing projects.
Anyway, my interest is less in bring more people into the fold (though that would be the ultimate goal) and more to continue to foster a sense of community. Obviously this doesn't require social media but SM is the going trend at the moment.
