Some or a majority of gaming “journalists” and outlets have always been more apologists/public relations to the video game publishers. It’s telling that these news sites have consistently reported on leaks, but suddenly stop to do so because, coincidentally, it’s a media darling: Insomniac/PlayStation/Sony.
I'm gonna preach a bit for my parish, but I don't think that's necessarily the case here. These kind of leaks are something new, at least on that scale, and when they happen they lead to discussions between the editorial board to decide if it's ethical or not to talk about it. Those discussions have happened for the Capcom leak, they have happened for this leak, and discrepancies in editorial behavior between the two don't always mean that journalists were afraid of being blacklisted by Sony, but, for example, that they decided that the difference in scale between the two leaks (especially in terms of the personal information released) necessitated different treatment, or simply that editorial teams have changed since then and newcomers have different ideas on the subject.
Personally, my point of view on this kind of criminally obtained leaks is to cover them if they have a journalistic interest and don't harm developers (typically, here the financial figures are very interesting), with a disclaimer at the beginning of the articles, but I know that others have a different point of view on the subject. I know that, as players, knowing the roadmap or having images of Wolverine in advance can be exciting, but revealing this kind of thing to as many people as possible can lead to the cancellation of projects, to a drop in morale among developers or crunch to rush the games which are now playable in their unfinished version. This is why you should always approach this with caution.
Of course, some journalists decide not to cover the leak for fear of repercussions from Sony (this kind of behavior isn't limited to gaming journalists, by the way: in all fields, journalists censor themselves to avoid losing money, information or advantages), but I don't think we should generalize about behavior that can be explained by several different reasons.
I'd also like to add that - although I have very little experience with Sony as I work mainly on Japanese games - no studio or publisher has ever complained about articles written about leaks. This may be different for American journalists, given their geographical proximity to SIE, however.
