As I said, I think it could potentially have been dealt with better. But practically? I don't know. What I know is that I don't have a solution to offer, thus I can't blame them.
True, I know nothing about comic hosting websites, so they sure should know better than me; I, however, have experience with times of crisis in small structures with only a few staff; with the mistakes, bad decisions and uncertainty brought by being understaffed and with too much uncertainly ahead to hire more. Sometimes even if you have a strong, serious plan, a good compromise, all ready, the beginnings are shaky and it may convey the wrong idea to the public.
I'm not part of Tapas; I can't entirely disregard the possibility that they decided they don't want to fight anymore for the creators; but at this point, I have no reason to think that, as the additional workload and confusion seem to be enough to explain what's going on right now.
