I think the fear is that one day the FromSoft suits will demand they start making their games easier so they can sell more. A fear that's pretty reasonable: they've already made one or two Elden Ring bosses easier with patches.
I'm not aware of anybody who wants the game to be made easier with no option to maintain its difficulty. People are generally asking for optional difficulty settings.
Having the settings exposed in the options menu changes the game, and the experience of the game, and the discussion around the game. I don't want the temptation of changing to a lower difficulty.
