If a harem route is something the dev wants to do then I'm for it, but for devs that aren't planning or have a desire to make a harem route then it's not going to be worth reading. It's like woodworking. I make some fucking awesome furniture. I can make a decent small crafts like picture frames, spice racks, jewelry boxes, etc. The difference is my heart isn't in it. I don't enjoy those little projects, so I don't do it much, so my skills aren't good. I don't give the care and attention to detail that's required to make them really exemplary. Game devs that don't want to make harem routes aren't going to put their hearts into it.
The same goes for really any aspect of a game. If someone jumps into a thread or patreon page and start pressuring a dev who's already shown resistance or reluctance to some plot idea, fetish, or game play style, then it's not going to work out well in most cases. Feel free to tell them what you'd like to see, sure, but leave it there. That's basically what the cucks do, but they still get a worse rap than the harem boyz. When a dev resists a harem, I've seen the harem crowd chime in with the economic benefits of doing what they want. "Dev~kun, why don't you make this a harem game. Most players are harem players if you don't know. They want to play and support harem games. If you make a harem route, your game would have so much more appeal. I bet your game would become so successful after adding a harem route, you'd probably be able to afford to buy several rental properties in Monaco or St. Barts." If they don't win him over with that round, they up the stakes. "You know, Dev~kun, that's a real nice game you have there. I'd hate to see anything bad happen to your reviews or god forbid... your paytreon. I mean, me and my friends was just saying how much we like your game. But it really needs that harem route. With a harem route we'd be sooo much happier, and when we're happy, you'll be happier. Trust me. Without a harem route, I think we'd be forced to let our opinions about this issue be heard, if you know what I'm sayin. Why don't youz just add a harem route, so we can all be happy, capiche? It's a win-win!"
