United in diversity
Simplification or "dumbing down" mechanics is a common strategy to reach a larger market, and casual gamers are a significant captive audience. The term is not intended to be derogatory in any way. If it seems so, we can consider using a substitute word, you can choose one that better fits the tone to your liking. However, my main point remains unchanged
Civ5 and Civ6 did streamline some mechanics, but in the meantime they also incorporated newer ones, like tourism, influence, loyalty, adjacencies and so on. So in the end, it doesn't necessarily make "simpler" games.
For instance, in Civ7 they removed workers because that was considered "tedious micromanagement", but now that cities are unpacked (meaning that they spread all over neighbouring tiles), workers just don't make sense as you build your cities all over its radius instead. I'm not sure that deciding on which tile you build your library to get the best adjacency bonuses is any less "tedious micromanagement" than building a mine on a hill.
Fundamentally, the core problem is that the game is always more guided towards an intended direction. It totally lost the open-end sandbox feeling of the earlier games in which you had no clue how the game would evolve when you initiated it. As a matter of fact, even Civ5 and Civ6 players complain about that about Civ7. If the purpose is to attract a broader more casual audience this way, I'm not sure that's a good one. Open-end sandbox games as diverse as Factorio, Stardew Valley or Cities: Skylines are all very popular, proving there's a large market for that. It's not just a niche.
