This.
All actors are manipulative, one way or the other, but her manipulation is clearly aimed at disqualifying young competition (JLaw and, to extent, Wallis who snagged a nom with a very first role) because they "didn`t pay their dues yet". I can sympathize with this but I disagree that JLaw is an overnight sensation who totally isn`t due. She has about as many great performances in the past few years as Chastain does in past 2. Plus both were already nominated so being older doesn`t equal due-er.
Anne-oying is pushing "Mom`s dream`s come true" because she knows that winners usually have some good story ("from trailer trash to Oscar winner" "my mom killed my abusive dad" "my granny who brought me up died last week" "battle of exes") and she thinks Mom who was Fantine understudy is a great winner`s story.
I mean, JLaw certainly isn`t void of manipulation. That Harvey joke at the GG was meant to endear voters who hate Harvey "look, I dared to say what everyone thinks!" (though Harvey would let her shit on his head if that`d earn them Oscars).
DDL mentioned Joaquin Phoenix in his acceptance speech. Like Anne-oying thanking Sally Field for being so old and Chastain thanking Bigelow for finding success at the old age, this was meant to show that DDL isn`t selfish prick who thinks only about himself but is generous to single out one of 4 losers. Now, I know that some stuff here does stem from real affection or admiration but it`s mixed with manipulation because when you do that in a public speech you`re aware that it`ll gain you points and acceptance speech is all about gaining points.
