That's not simping for Amazon. Simping would involve saying something pro Amazon, no one is doing that.
You're right, no one should be taken advantage of, and if a job isn't worth paying a livable wage for, it's not a job that should exist. It seems like everyone agrees "influencer" isn't a job that should exist.
Influencers don't work for Amazon, they're free to try peddling their nonsense somewhere else. But it turns out they don't actually provide a valuable service to anyone, so no one wants to buy it.
