"I didn't rape Aleah, I welcomed her into my castle as a maid where I and the other maids take good care of her and she is happier than she has never been before. This makes me feel satisfied, it is nothing like how we treat Alina when we meet her."
even the "good" options still show a great deal of immorality and possessiveness. your argument is that its ok to gather girls and keep them as house pets just not slaves. Would renryuu have done the same thing if she where ugly. if you put yourself in aleahs perspective would be i can be a prostitute to 1 guy safe in a castle or a i can say no and be a street beggar and have to prostitute myself for money. However despite this they do form a genuine relationship over time that is more since. the fact that despite the sad start to there relationship she does eventually fall in love with the protagonist is really not that different to alina in harem collector. Harem collector just more confronting and dark about the same scenario
Felt i should also mention in renryuus ascension the only way to get a party members affection high enough to sleep with you is to drug them with love potions. you see why people are finding your comparison completely hypocritical. or if you truly do use renryuu as a player insert where his actions align with your moral compass. all though you probably never stopped to think about the dark themes presented in renryuus ascension or just didn't care because renryuu can let you pick the lesser of two evils. In harem collector the dark themes are a part of the games story and world so you cant just pretend its not there. Then the only reason you don't find renryuu's ascension offensive is that its more discreet, (assuming you do the "good" choices). If harem collector gave the player the choice to make to be a cliche moral hero it would make all character growth, dialogue and story become inconsistent and pointless.
and the idea that you think someone shouldn't make something if it doesn't align with there beliefs is so retarded i'm not even gonna bother refuting it. let me guess you probably never watched game of thrones because in your mind George R.R. Martin must endorse rape because main characters in the book rape and get raped.
If you put aside your biases and hypocrisy you might find you enjoy things a lot more, just remember games are fiction and its ok to enjoy and appreciate the content that is there even when it doesn't align with your beliefs. Or maybe instead you can ask the dev to add a SJW game mode that lets you skip scenes that might make you uncomfortable.
