I can't speak for everyone, but I would rather cancel my account and uninstall the game than ask for help in-game. I hate to depend on others with a passion, and in a game — something that I do for fun, for enjoyment, and that I can quit at any time without further consequences — I simply won't ever depend on other players.
Now, I'm kinda an extreme example, but for other players that don't feel comfortable with co-dependency, Wings basically made trading in Open far less enjoyable. Suddenly the chances of meeting groups of players increased, and for those that don't like grouping up themselves it means a far larger risk of the opponents having overbearing force, a risk that can only be mitigated by something (grouping up) that for them makes the game less enjoyable.
