While the reaction in the OSR circles has been mostly positive (with a few "this is obvious," "you're late to the party", "you're preaching to the choir" comments) the "general D&D" reaction has been mixed.
In the D&D community, I've got positive and negative comments, and even a few vague defenses of fudging die rolls (especially for new players or low-level PCs since the system is "too deadly"), but not really any extensive defenses of fudging. Maybe the most elaborate response I got is that dice are there to help you tell a story, and they should be disregarded if they hinder the story.
(Even if you think RPGs are meant to tell a story, I do think fudging dice WITHOUT players knowing this possibility is tantamount to cheating. Detailed explanation here).
It might be a particularity of these two communities... but I do not think so. I think this may point to a fundamental difference between OSR and modern D&D. I am certain that many 5e players and GMs find fudging dice abominable, but at least the idea is more or less acceptable in "modern D&D" circles.
I do not think, however, that this is entirely intentional. The lack of an elaborate argument in defense of fudging and even the lack of honest communication (i.e., DMs fudge the dice without telling the players that this is possible) indicates to me that this is an habit that "modern" DMs adopted without reflection.
Let me reiterate that I do not object to whatever play-style you choose. However, I'd encourage you to reflect on that and choose what you find best.
I'd also love to see a coherent defense of fudging.
I am thinking of at least one argument myself: I think PC death is a PROBLEM to be solved and not only a preference (something I address by the end of the last post but deserves a post of its own, coming soon).
