If I tell the players I'm changing a crit to an ordinary hit so as not to kill off Falstaff it is fudging every bit as much as if I do the same thing and don't tell them.
Fudging = arbitrarily changing a die roll from something undesired to something desired. Whether or not you tell anyone about it is irrelevant.
Totally agree
Totally disagree. Reroll mechanics have a very strong place in the game and are, IMO, an excellent design. It might be something you don't like, but, that doesn't make it poor design. The evolution of fudging mechanics in RPG's is pretty clear. We started with most of it being hidden behind the DM's screen and it has now moved into the open and can be planned for.Reroll meta-mechanics are just sanctioned fudging IMO, and are thus poor design. Edit to add: poor design in an RPG. In Yahtzee where re-rolling is a built-in part of the structure of the game, it's fine.
Think about it this way. The developers couldn't know that most groups were going to fudge their character creation. Paladins were rare because you needed high rolls to get one. But, if people are just fudging the rolls, then paladins stop being rare. Same with rangers and druids and monks. All that gating of group power behind die rolls during chargen goes straight out the window as soon as the rubber meets the road.
So, you can easily wind up with a group of six PC's that include a ranger, a paladin and a druid/thief/MU.

When fudging is purely ad hoc DM fiat, there's no way to design around it. When it's player facing and defined, then you can start to incorporate it into your design decisions.
