Hemphill clarifies that he did disclose to Meta during his deposition over a year ago that he and former Biden official Tim Wu had a “conversation” with the FTC in 2019 about investigating Meta, but the company never asked him for a copy of the presentation. He says he wasn’t compensated for it, and wasn’t retained by the FTC for another two and a half years — during which he also didn’t lobby the regulator to bring a case. He says that public reporting of Meta’s conduct “seemed like the kind of thing that we’d been worried about in our academic work,” but that he hadn’t formed a view at the time that its acquisitions of Instagram and WhatsApp were anticompetitive.
