Why do people get twisted up in GF's wordnado? He says the players should respect the fact that some playstyles need cooperation to be complete. GF is looking to spend his time pursuing other players goods, and for those that take up play in open to respect the push and pull the food cycle requires. I can totally sympathize.
The fact remains, no one want to be the victim. No one, well not enough lets say, wants to be the sucker out the profit. Along with that natural inclination come this strange stigma put on players that don;t care for open. The assumption that open is the true path, and everything else is some admission of lesser ability and/or status. Post after post, comment after comment labels the Solo/Group player as inferior, some how lacking. Rather than the overaggressive and tricksee labels that come with the open only player. Labels more comfortable worn by a bunch of gamers.
This loss aversion, and keeping up appearances causes players to play in open, until a threat arrives. They can say 'Oh yeah I play in open' to their in-game friends, while still being unwilling to cough up loot, or die for another's gaming experience. Take it as it is, this is what we have. Timers, and splitting hairs about what is and what isn't CL'ing only serves to foster this gap.
REmove the stigma. Accept that all play styles and environments are valid and necessary for a healthy game, and maybe players will feel comfortable playing where they like. Removing that false hope, which is worse than no hope, of having willing Commanders in open, ready to go the distance.
