You know what, to me that does not make sense. The reason I say that is if it was one translator moving then that person might not have been accepted because of the agreement you mentioned. But if there is a whole flock of them and especially those that have started on gravity, it looked there might have been a much more serious reason for the move than the easy license. To me, there was clearly something that gravity did that didn't make them feel at home and wanted out. For people to reach that point, especially a lot of them, means something has gone seriously wrong.
