Swearing doesn't help and it's not impossible.
But i can agree to you to some extent.
Talking about Fallout(I'm sure you're talking about first two ones but 3rd one is closer to AP as design) haven't you gone in small arms skills in third game? Did it make you think like "Oh i can't convince super mutants not to attack me by talking... This game is ****ing ****!"
You can use some speech skills which are availible in renegade/paragorn in Mass Effect but again boss fights are fights after all, even in there. And in AP you can use dossier information on people while talking or again choose to spare or execute but boss fights are boss fights.
It's not all about Obsidian or Alpha Protocol or any other game really, it's the state of whole sector(aka I r h3ro, i r l33t l0lz)
Developers in RPG or MMO sector generally thought they'd reach to a smaller but dedicated player base since start. But since WoW's success on masses they thought it might be better idea to influence casuals while don't caring much about hardcore or power or dedicated player base.(Or let's say concentrating on casuals since they're everywhere... I mean millions of people play WoW while "not so carebear friendly" games only reach to a few thousand sales) Even if developers would care distributers wouldn't allow them because money is important in life eh?
So that's when instead of supporting/using or thinking about different approaches to gameplay they decided to give people what they want. Players generally want instant glories, feel like a hero, want to "pew-pew" whole way around, want to be "leet", instant/fast paced gameplay which rewards them with no real reason at all... So why wasting resources that only for a few people while you can please a larger audience in other way?(Money, distributor's greed or it can be about even reviews... Just check how many adventures released this year and also check the same thing about FPS's. Not many people like talking, investigating etc but shooting them in the face! Sad but true =/)
It always works in same way in nowaday's games(excluding good old Fallout I-II etc since it's sad but their golden times has gone) so why choosing AP to rant about?
PS : Btw gameplay wise... i'm glad that AP isn't so "casual housewife" friendly that you need to aim at least. Too bad Obsidian gets flamed by "poor combat mechanics" because of that
Just because the majority of gamers are quick-twitched insta-reward types doesn't mean every single publisher and game developer is going to pander to them. In as much as they are the fastest growing and easiest to please crowd, does not mean that the other gamers who require a more deft touch are disappearing or suddenly deciding that "simple" games are for them.
