Yes, exactly, that is the question. And the answer is that they’ll let other players do the work as long as costs remain reasonable. If a bunch of industry players ragequit and prices go up too much the PvP players will just build their own stuff, and may even run industry operations of their own to exploit the opportunities created by high prices.
What CCP needs to remember is the crucial balance between these activities and their challenge is how to keep them working together in harmony.
And they are remembering that balance by creating new opportunities for smart and ambitious industry players. The only people who lose are the ones who insist on a “play style” of zero-risk passive wealth accumulation, and those players add almost nothing to the game. If they do ragequit over this their minimal contributions will be easy to replace.
