WHen it comes to accessibility, there's a ton of variability in what different people need. Controls are so important that Microsoft has many features to help gamers, including their adaptive controller and co-pilot features. Any UI feature that's awful will get magnified for a different group of people. Requiring a ton of button presses to navigate menus and get information that should be readily available can be significantly more time-consuming for people with some needs.
You're comparing the game to the status quo in an attempt to argue, when the complaints also apply to the other games. This makes the status quo comparison pretty useless as a point of basing agreements. The article's title clearly states that it's relative to Microsoft's standards -- not other similar games. Microsoft has invested millions of dollars to develop accesssibility features and improve the lives of many gamers. They have a number of options and features that may be improving some of these games in ways that you haven't used if you never make use of the features. Now that Bethesda is under Microsoft, one might expect them to utilize and improve some of these issues. As with many accessibility issues, many of the complaints they raise affect not just people who rely on accessibility, but they affect us all. I think just bringing attention to them is a good way to finally get them fixed.
Bethesda's menu system has been so awful for decades now, and they still repeatedly fail to fix it. It's so bad, it's usually one of the first mod fixes. They build their games around inventory management, and make it as tedious as is humanly possible, which because even more tedious if you have some challenges related to input.
