What I read from this forum sadly look like the breaking of a family of fans. I understand what the translating group are doing as they still want to read the series without getting sued, but to the extend where they hold it as "it's mine and I am not sharing".
I think this is where you really go off track, and a lot of the rest follows from it. The translating group isn't opposing other translations because they're being territorial. They're doing it because they respect the wishes of the author who's specifically said they don't want scanlations floating out there. The Halmoni translation via overlay works because you still need the original to use it, which benefits the author. The other translations being discussed, on Imgur, Tumblr, etc. are opposing the wishes of the author which is an important distinction.
As for Dynasty, part of the concept of this site is to respect the wishes of the original author and those of the scanlators who volunteer a lot of hard work to bring us English versions. Supporting the authors and the overlay group in this situation is a no-brainer in light of that.
