i would contend that griefers "believing they've won" is much more a response to Frontier's action (or inaction in most cases) than to any group of players choosing to play in a different mode. and really, the only way to truly be safe from griefers is to simply not log into the game.
Or play in solo where the chances of any
direct griefing by another player is demonstrably nil.
I've always thought of the modes as being similar to bars.
Solo - sinking a few cans in the house on your own
Private group - private member's club, you get to mix with people but only those who can agree to abide by a set of rules
Open - your local dive bar where anything goes
That's not a criticism of open at all (or either of the other two modes) because you can have some of the best nights of your life in that dive bar but some people will sometimes want a drink without the attendant unpredictability.
i would further contend that individuals using private group modes to simulate open play is no less griefing than a griefer infiltrating a private group in order to simulate open play.
I don't think you can reasonably contend that's what they're doing though. They are playing in private groups for many different reasons but one that does seem fairly common is to avoid PVP. Since implied consent is given to PVP upon entering open mode, the very fact that players are choosing to do something else strongly suggests that they're not trying to 'simulate' open mode at all. That's without getting into the fact that there is no need to simulate open mode because for players that want to play in it, there is err... open mode.
Obviously I
am just breaking your balls a little there, I know what you meant, but the point does stand - those players are fundamentally
not looking for the experience of open mode since an intrinsic part of that experience is a form of gameplay that they have no interest in participating in.
The thing is, FDev sold them a game which allows them to opt out of it via private groups, in exactly the same way as they sold PVP aficionados a game which allows them to
'just kill other Commanders' in open mode. The old
'FDev's marketing said we could do...' can't be used as a prop for one leg of the argument and disregarded when considering the other.
As noted above, doesn't really apply.
Edit:
Specifically about this though:
i would contend that griefers "believing they've won" is much more a response to Frontier's action (or inaction in most cases)
I would have to concede that you may well be right.
