People don't dislike Fallout 4 for the introduction of quality of life additions, they dislike it because it has poor writing and design, especially for an RPG but even for an open world shooter. The shooting mechanics are OK, but not good enough to carry the game, the loot system is simplistic and becomes boring after a few hours, the quest design is typically awful, along with a large majority of the writing. Combine that with the extremely limiting and ultimately pointless dialogue system that was dumbed down, not to make the game more accessible, but to add voice acting that really does nothing for the experience, and you start to understand why RPG fans hate the game. Don't represent the complaints about Fallout 4 as complaints against QoL and accessibility changes; most are complaints about bad design.
