I agree with you
It's not that the critics of her works started here. It's that some people here started tweeting her for support. The English Tweets Sensei didn't understand started here. The rumours about her being upset by comments were false--which is one reason why she might not know why people were tweeting weird things in another language at her. I think there was also a translation problem, which is why she tried to explain she didn't need sympathy. I think many things may get lost in translation both ways.
So keep this in mind:
(1) Comments here are readers talking to other readers. There is little chance the mangaka hires a translator to see what people here think (especially since everything here violates her copyright and you cannot buy this in Engish). People can say whatever and the only repercussions are that others will disagree. No one is really talking to the mangaka, even if they somehow imagine she would care.
(2) The comments in this update probably refer to her making changes in volume 2 by adding material. They don't mean she is quitting or being censored. From what I have seen, yaoi editors don't usually care whether the sex is consensual so long as there are enough naked bodies per chapter. (FYI rumour has it Ayane Yamane added a sexual assault to volume 8 of Finder because her editors wanted more sex in a given chapter).
(3) When we read translated comments that say she thinks maybe not everyone likes Caste Heaven, maybe it's more along the lines of, "Hey, I know this may not be everyone's cuppa tea, but thanks to all my fans." It doesn't mean she is necessarily upset.
(4) It's all a tempest in a teapot anyway.
I just really hope this story goes on! It's so freaking amazing... I love it so much (●￣(ｴ)￣●) I' m a total fan
I read in another comment that the critics about her work started here in mangago. I think it's really sad 'cause there are lot of people who don't respect enough the work of mangakas. They can be really rude: it will be great if people who just don't like the genre could not say unecessary thing to the authors!
