I assume it is PR. Previously, broadcasters and their journalists held some bargaining power in interviews such that in exchange for being able to access a broad population, the interviewee would be willing to subject themselves to the journalist’s questions.

The internet kind of obviated that role, so now there is no need for an interviewee to subject themselves to questions they do not want, because they can reach everyone they want at no cost by putting up a blog post on their website.

Bingo. Discard this so-called interview as a fluff piece. It provides no signal.
