@Davincen Socialist ideology out of your mouth at its finest.
What you're saying is this " if you don't support it, you don't have any right to criticize it".
Imagine if all ideologists can get away freely with their anti-human ideology because non-supporters are not allowed to criticize it.
National Socialism and Communism would be as lively as they were in the early 20th century.
It's because at least some humans are intelligent that we get to criticize the products of the human mind (art,theory,ideology,philosophy,religion,etc.) regardless of our support or not.
In fact, an intelligent person will first analyze if it's worthy to support and only then invest time & money if deemed worthy, only an idiot will buy the literal cat in the bag,especially since it's part of marketing strategy to deceive potential customers into buying things they don't need/like at all.
It's very strange to "reason" on the aspect of financial support, simply because the initial product was paid for,then multiplied and then changed (in this case by translation and/or redrawing).
If for example a person on the street sings a song that is sold on CD, will you abstain from criticism because you didn't buy the CD of the singer/composer?
By the way, you can read the first 2 chapters for free on the official website anyway, which would allow you at least a pivotal lever to criticism on your terms.
The way the story develops is locked behind a paywall, but it's not as if there has been any major plot twist so far that would suggest you need either an IQ of 300 or scanlations to predict the outcome of the story, so far it's running pretty linearly, the good are the good, the bad are the bad, the masterminds are still the masterminds and the plan stays the same for both factions.
The way it's written is precisely the reason why it is perceived as bad as it is by many readers, it has the same problem as most ordinary modern stories categorized into the "harem genre", a male MC that doesn't entertain the idea of having more than one lover (but compromises on her clone it seems), female characters trying to seduce the MC relentlessly, an evil organization/entity as "main plot" to distract the reader from the fact that the story is about a man with woman troubles( i.e. a completely boring premise), continuous introduction of new characters without leaving the old behind (i.e. "magnetic overload" at some point) and the complete lack of suspense because of Deus Ex Machina in the seemingly toughest situations that are directly and completely resolved.
You get from this story what you should expect at this point, it's irrelevant if this sort of story is set in a fantasy world, the modern world, an apocalyptic world or another world completely (i.e. the infamous "isekai" genre).
