I'm not sure why it's relevant what the player feels. If they don't like open mode they have 2 other modes to choose from or not play the game.
Are you perhaps thinking that ED will die because it is too niche? I'm afraid that ship has sailed, open mode is what it is and FD have been very clear that random PvP is allowed. It's up to each individual player to deal with their feelings and adjust how they play the game accordingly.
I stress that I am on the fence here and I am not sure what constitutes griefing but seeing as some have called into question what the definition on griefing is, what is your definition of PvP? Is it 'anything goes so try not to feel butt hurt, just take the meds' or is it multiple ships that all have a fighting chance of winning or at least surviving the encounter?
I suppose it depends on how your mind works, I have decided not to press home attacks on Sidewinders and Eagles with low bounties unless they are really bugging me but that's just me.
On the other hand some people get almost militant about people who move from solo to group to open play and so on when in truth it is none of their business how people play. Or is it? Because if it is and they are right then OP has got a point hasn't he?
Opinions are like bum holes.
