Also i have the impression that groups like mobius in reality are unhappy with the game and it's features. Because if i would be happy with the feature of maybe encountering an enemy player, why would i choose to dodge this?
We* are (more or less) given a choice of when to meet an enemy player, it is a choice that for us makes the game better — often much better — and we cherish that choice. Even some of us that play mostly in Open, and thus that choose to be available for PvP most of the time. Simple as that.
Or, in other words, we are happy with the game, or at least with this specific feature. We wouldn't be happy if the choice of modes was removed from us.
And, for the record, from the start DB made it perfectly clear, and repeated multiple times in different ways and venues, that players would be able to choose who they interact with, and he explicitly mentioned that choosing to never meet anyone else was a perfectly valid choice. If you don't like the fact that any player can choose to simply ignore you and never ever meet you in the game, then the one that has an issue with how the game works, with its features, is you; those of us that choose to not meet you are just using an explicitly promised feature of the game in its intended way.
* generalizing a bit, but from this thread I guess it's fairly safe to assume that this applies to many, perhaps most, of the players that are defending mode switching.
