yeah I watched that when it came out in 2017, I thought in the end the influencer was depicted as a good person who's earned her status, no?

I would not call her a good person. Almost nobody in that film is a good person.

In the end, the influencer is depicted (accurately) as a victim of the protagonist's mental instability and manipulation, but it's her vapidity and inability to genuinely relate to anyone that made that victimization possible. She's as damaged as Ingrid is, just in a more subtle, socially acceptable way.

There’s a subtle through line that the influencer couple were just boring, born rich people using the whole Instagram influencer thing as a means to launder themselves into something more hip and bohemian (and thus marketable in contemporary culture). Ingrid, being a lower class person, is drawn into this deception and they ultimately come out in more or less the same places they started. If I remember correctly, one of the influencer couple at the end is moving on to take a corporate art job (without any real merit or qualifications) at Levi’s or something.

Yeah, it's Levi's.

I didn't read class in the film quite the same way, but that's an interesting lens. I should watch it again.
