I mean, yeah? Doesn't take away from them still taking inspiration from the ultimate universe. All you're doing is explaining why.
How is that taking inspiration from the ultimate universe?
The lineup was the 616 lineup until Wrights movie got canned and rewritten during production.
The chitauri were clearly subbed in for skrulls, and basically never really expanded on other than being cannon fodder for the Avengers to shoot at. The skrulls on the other hand got a whole movie to explain the Kree/Skrull conflict... Which is a 616 thing that goes back to the Kree/Skrull war Avengers arc.
There is VERY little influence from 1610 compared to the obvious and direct influences taken from 616.
Cap 2 (Winter Soldier) is adapted from the 616 arc.
Hawkeye isn't close to the 1610 version either- despite having a family in the MCU, Hawkeye turns into Ronin in Endgame- which never happened in the Ultimate Universe. That was a 616 arc and he's in the 616 Ronin costume.
The MCU Ant Man is adapted from 616 Scott Lang and isn't influenced at all by 1610 Pym.
Age of Ultron takes its title from a 616 arc, but the basic storyline is adapted from the 616 Avengers arc where Ultron is accidentally created by pym them goes on to create the Vision. It bears no resemblance to the 1610 Ultron and Vision.
Cap 3 is an adaptation of the 616 civil war arc, though massively scaled down.
Guardians of the galaxy is ripped wholesale from the 616 Abnett and Lanning version of that team.
Thor:Ragnarok is an adaptation of (strangely) the 616 Planet Hulk storyline, with only a handful of Thor stuff sprinkled in.
Black Panther is adapted from the 616 Rise of the Black Panther storyline where the panther/kill monger conflict plays out almost verbatim.
Infinity War and Endgame are adaptations of the 616 Infinity Gauntlet storyline, and the 616 "Infinity" storyline.
There is virtually no ultimate universe influence in the MCU, outside of Sam Jackson and a handful of superficial things. 99% of it was adapted from 616.
