Somehow this very vocal minority has convinced the devs to dumb down the game to the detriment of everyone else.
Everything I've heard about the development is that Taleworlds makes these decisions basically on their own and then uses player complaints to justify it. For example the ridiculous limit of 6 colours for banners was solely Armagan's idea. The Class System that is the root of so many issues in bannerlord was implemented despite half the (outspoken) developers and the majority of the playerbase thinking it was a terrible idea. One of the MP devs even said that "the VAST majority of players loved it", only for Callum himself to say "where on earth are you getting that figure from". This was during the Beta.
Most development studios are stubborn, insular and basically shut off from the outside world. It's just the nature of closed team-based development. What this means though is that whenever you hear about a "vocal minority" influencing the way a game is developed, that is basically never true. The decisions are never made by looking through forum posts or twitter threads or whatever, they're made in endless meetings between a small handful of people who have their own goals in mind (sometimes petty rivalries or personal ego). They might abstractly consider what their customers want, but this is usually through their own lenses rather than from actual feedback.
From the outside, when a nonsensical decision is made its easy to point the finger at some group of people who it seems have twisted the developer's hands, but this is almost never the case.
