You can reasonably grind like 85% of the poses for 3-4 characters with almost zero effort. You should very obviously start by focusing on the first 1-2 you like the most and pick those character packs. If you spam a non-character pack and get duplicates or get poses for characters you do not want then, yeah, it will be grindy because that is insanely inefficient.
I haven't looked at it in a while so the only thing I have to go by is my own past experience when unlocking the engineer girl. What you said was, "
Are you someone who likes only 1-2, maybe 3, specific girls currently out? Not a problem to unlock the vast majority of their poses completely free with minimal grinding and zero money spent beyond the $36 to actually purchase the game" and I commented on that because from my experience, that wasn't true. I focused on one singular character using the currency and booster you get that comes with the $36 tier and still didn't unlock all poses for her.
The exception is if you want to collect every single pose, no matter how trivial the pose is even if you wont use it or for characters you will barely touch... that becomes more of an unhealthy achievement hunting problem than an issue with the game.
I also commented on this because it's a pretty weird outlook when it comes to games. If you look at Elden Ring for example and you see someone that wanted to obtain all spells the game has to offer, would you consider that an unhealthy achievement hunt? Is it really odd to expect that someone who paid for a game would like access to all the content they paid for without hassle even if they might not use it all the time?
Alternatively, for a couple of dollars you could just pay away the grind like many MMOs and such allow. Personally, I'm level 8 in the game and have around 75% of the poses unlocked for Alet and quite a few for Erika/Anya (probably around 40% give or take). I'd play more but I'm not a fan of the current roster of characters.

As for spending the initial $36 on a porn game, if that is a problem then don't and enjoy free porn. This isn't even an argument that would make sense to have.
Combining these two points. I think you misunderstood, I wasn't saying $36 or any amount of money was the issue here, it's that what you were suggesting was to pay the initial price then also chip in extra as a means to skip an annoying grind just to get a portion of the content you paid for. Unlike MMOs, Fallen Doll isn't packed full of content, all it has to offer is its porn. In MMOs a lot of the time you have to do x, y, z and that can take you a while to get to where you want to be to comfortably play certain content available, and in those cases, I could see MTX to skip grinding making sense. Warframe is a great example of this. In Fallen Doll there's just porn locked behind a grind purposely made annoying to encourage extra spending just to get a slice out of the whole pie you purchased.
Naturally, almost any game you play you don't just get "everything unlocked" without grinding. Almost no game, except the most linear of games, function this way.
This is true, but Fallen Doll Operation Lovecraft started with this function. Before Harem mode was introduced there was only Gallery mode that offered everything unlocked without grinding.
The online requirement complaints are, in fact, quite stupid. The game wants to fight piracy specifically because, oh look a mega 700+ page piracy thread with people who are so desperate they will willingly download malware hoping it has up to date content and beg without reading instructions for the newest crack. Porn is one of the most pirated media, too, and it essentially destroyed the most prominent porn game company, Illusion.
You can add whatever anti-piracy methods to a game and still not have it be online only in the sense of forced multiplayer. See Helldivers 2 as a more recent example of this. An online only game with GameGuard that offers both co-op and single-player.
And from what I've seen from a lot of people that actually own the game in this thread, the issue is less about Helius trying to fight piracy and more-so that in doing so he completely changed up the game from what a lot of us originally supported, which is why you had people that actually own the game using the cracked version instead of the live version before the game updated beyond v0.49. This thread has hundreds of pages but a lot of the usual chatters are older supporters.
As for the complaints against online components there hasn't been a valid one yet.
It isn't up to you to determine whether someone's preference is valid or not. You can have your own
opinion on the matter and that's fine, but it'd be no different than me saying this game doesn't need females curvier than Anya then saying people that disagree have no valid reasons to disagree. It's preference. You may prefer or like one thing, others can like something else. The script can be switched and I could ask you why this game needs forced multiplayer then claim you have no valid responses.
