Because the game is old and hasn’t been worked on in years. They’re no reason to even think about turning off updates for it unless you happen to know the random years later update is coming.
But I learned the hard way awhile ago with Xcom 2. They “update” that all the time, but don’t do anything to the game, is just the shitty launcher they keep updating every month.
What really gets me, and this touches on your comment, is that the execs said that they need to have the teams make what they specialize in. And then they turn around and force all the studios to make games that not at all anything they’ve ever made before.
