They either don't read it or just don't care lmao. This is one of the most discussed topics here as well as their Discord and in 6 months they still haven't changed anything. Larian is telling you they don't care if you don't like how her interactions with Halsin were written by choosing to ignore this feedback while implementing countless other things for other characters in the meantime. You either ignore it as the out of character fanservice and/or self-insert garbage that it is and get rewarded in the epilogue or you romance someone else because nothing is ever going to be changed.
