The game in question is Fallout 4. It’s a single-player game with zero online components.
Just like with Morrowind, Oblivion, and Skyrim, as well as Fallout 3 and New Vegas mod support is an actual feature of the game with officially released tools and documentation for creating mods.
Given that, the fact that mod support was a major selling point for the game (IMO the only selling point), and the age of the game, it would have been better if Bethesda stopped supporting the game altogether rather than push updates with no meaningful changes that break a feature that for some people is the primary feature of the game.
