Because excessive baiting and author's past brought yurifags into the equation. Having character with a dick in "their" manga is a big no-no, and usually elicits screeching. For large part of that fandom it probably comes down to something like narcissism mixed with feeling that their identity is being threatened or invalidated, hence the opposition followed by exaggerated reactions (which are genuinely creepy, as most of these people are at least twentysomething, often older).
It seems the new group aren’t really serious translating this. It’S been 4 months. Anyway
the new chapter is out, the chapter 57, and Kuzushiro the author reassured in this chapter that this isn’t going anywhere but straight. Oh, I love their development as sisters.
