the grifting probably refers to the fact that her staff did most of the work - guests mentioned they were interviewed by staff not Meghan and an ex Archwell member posted some comments to that effect too with some choice comments
Rebecca Sananes complained about this Hollywood Reporter article

Her complaint is about the article and how the power players are the celebrities, executives and agents and there is no mentions of producers who Sananes believes (and rightly so) do the hard work. Because of the podcasts she said she created (she mentioned 2) - it was spun by many as an attack on Meghan (not mentioned in the article) and strangely not on Kara Swisher - who was actually mentioned in the article. Meghan indeed interviewed the celebrities in her podcast and the producers interviewed the contributing guests - this is pretty much standard for these kinds of things and would surpirse many in the podcast industry that they would be considered grifters for doing this.
