Todd hasn't made the game less hard, Oblivion was more difficult than Morrowind and supposedly Skyrim is supposed to be more difficult than Oblivion as well.
Well not Oblivion was not difficult at all, all "difficulty" of Oblivion was in health sponges from broken leveling, so need to boring long combat with such "Difficult" enemies, don't forget about so hatefull by You staggering in combat its still present and work even if strike doesn't make significant damage spellsword easy work since Magicka regenerates overtime as well as health on waiting, fatigue almost not run out and doesn't affect casting at all, we can block and parry any strike, backpedaling in combat makes archers and mages playing FPS, constant enchants and no enchant limit make mages almost invincible from middle of game if not earlier, Alchemy thats always work and ingredients thats can be found without problems make easy cash and support in battle, no guild requirements makes even barbarian an archimage, no level requirement for MQ make it happy safari into Oblivion to hunt some scamps, lock picking can be done almost without lockpick loss and at any levels of security, no static enemies thats make area hard, free restore of attributes in chapels, fast leveling of skills, fast travel thats almost hot has requirements and quest compass what always show where need to go, too much ambient lighting in dungeons make torches and light spells useless, and forget about this
http://www.youtube.com/watch?v=0wK9dc_O3pM , definitely Oblivion was not difficult at all, too much depend on Player skills too much does not affect player, too much was easily available without of any hard work.
But I don't say Morrowind was difficult game, it was more difficult then Oblivion because of much depend on dice rolls and then on player skills skills of characters need to be leveled while skills of player independent of it, static treasures was easily available if you know where to search, certain spells make game to easy, chained alchemy and enchant suits allow creating uber characters, but most of exploits in Morrowind was learned after playing game need to know such flaws to use them they was available mostly for experienced gamers, while most of exploits in Oblivion was available right from beginning of game.
Some exploits of Morrowind was fixed in Oblivion like chained alchemy, but they generates new ones
Most of exploit of both games was fixed with mods, modded game almost finished game.
Todd exactly make game less hard at last from beginning, does he say about removing of birthsign for protecting from bad choses from beginning, but from other side fixing some exploits from Oblivion like backpedaling, does thats goes into circle?
Skyrim must be more difficult then Oblivion was.
What I don't like its the way how they fix flaws, its mostly based on removing of features instead of fixing and improving them, but I admire they fixing flaws even if sometimes such fixes uncertain and doubtful.
