You seem to be missing what is being said regarding "Raise dead/magical items/etc'.
It's not that "D&D ripped this stuff from video games", but that "This makes D&D feel like a cheapened videogame, as opposed to a fantasy story". Where your character is just some numbers and you're killing things to get better stuff to kill bigger things. That's as monotonous and faceless as any video game.
Death isn't final or even epic, it instead is "Oh, well I'll be back as soon as you get back to town". +1 Longswords then +2 then +3 makes magical items into just a nameless thing for a mechanical bonus to be better only to be discarded when you find a better one. As opposed to a Named magical creation with a long history that you want to learn, and keep with you.
So, the stuff that makes D&D more like a video game (of a faceless hero just killing stuff, death is just an annoyance, items are just stat boosters to make him better at killing) are the things that have always been there, rather than the New Ideas stolen from MMOs.
