They mention GTL on their website as their game, even while they 'out sourced' most of the work to the studio in London (current Slightly Mad Studio), so it's nothing more than normal that they keep the online part of the game up and running imo. It's more their duty, certainly not something extraordinary they're doing imo. I would be very thankful if they would fix some of the GTL bugs, but I'm quite sure they won't.
