As an example, I would say that the Skyrim interface is “dumbed down.” By which I mean both simplified and accessible. Being both a TES veteran and playing Skyrim on the PC, the inventory and perk menus seem clunky to me and difficult to navigate. It’s almost as though they were designed to be viewed on both a 60” TV screen from 8’ away and a much smaller higher rez monitor from 18” away. Crazy, right? But just because I think an aspect of Skyrim is dumbed down because of console limitation does not mean I think people who enjoy the game on a console are “dumb.”
The differences are not limited to the hardware the game is run on. I believe certain mechanics of Skyrim are “dumbed down” when compared to previous TES titles in the sense that they’re much less complicated and there are far fewer choices. Those of you who played Oblivion without any leveling mods know that leveling your character efficiently was almost a mini-game unto itself. Leveling in Skyrim is much more straightforward and simple. I admit, I am the type of person who would create spreadsheets and calculate in great detail to min/max the stats of my table top RPG characters; to me, that was part of the fun. But obviously, I that is not fun for everybody and I would never be angry with someone for wanting to simply immerse themselves in the world without worrying about making a sub-optimal attribute point allocation.
The best anology I can think of, is the difference between driving a car with a manual and automatic transmission. They both will get you from point A to point B. Manually shifting offers greater control and performance, but an automatic transmission is easier and more accessible, letting you sit back and enjoy the ride.

In fact, as far as RPGs come, it's one of the most accessible games out there for people who have never touched an RPG before. So to take a game like that and try and simplify things even more for people who don't like open-world RPGs was too much. For RPG fans, there's barely anything left.
Some developers want to make as much money as possible, while others want to make the greatest game possible in a particular genre. You can't have it both ways. You can't appeal to everyone while also making the best product for a niche audience.
