I'd like if there was an option for my scanlations being open to everyone. I don't do my scanlations for money or fame, I want as many people to read them as possible. If only batoto members will be able to read my scanlations then that defeats the entire purpose. Who cares if other sites copy your shit? It was never yours in the first place. The mangaka and the publisher own the manga and all its derivations. Scanlators are just doing public service.
i dont know the particular agreements you took with batoto, but i dont think they took the responsability to spread your work to other sites. i understad where you come from, but batoto and other scanlation groups need to converge and focus traffic for their work to their own website in order to cash some money for at least covering the expenses.
your uptake on your job is exemplary and as a common leecher i cannot help but commend you, but i dont think batoto and the other groups are to comdem because they wan to regulate the flux of people enjoying their work for their benefit.
