Being on the internet doesnt mean you can say anything just beause you think someone wont see it. Anyone can screenshot this web and shares it to the author (it happened before). Bare minimum of acting in public space on the internet is respecting everyone. Unless you're on a private account ofc
Also constructive critisism isnt the same as complaining, whining and plain hating. Critisism while demanding something is unethical too. Giving actual constructive critisim is different with asking something different based on personal preference

Some of you folks are like those bad birds in vivimeng fandom who complains when they got fed new food from the content they decided to follow through. You got new content but you're trying to control what the author makes, "oh my god I hate this, why author why, it should be this instead"
Write your own story if it bothers you so much you start being disrespectful while consuming this for free. "Why cant I have my opinion ueueue" well freedom of speech come with consequences and being polite and respectful is the bare minimum. You dont even pay a cent for this, why would you whine like the author shoves the story to your nose?
