Yeah, I'm a bit disappointed by all this too. But it does go to show that one or two people's hobby, when it becomes profitable, goes away when the principle(s) leave. I don't think Anandtech or Techreport thought they'd get this big or to be something that they'd manage for the rest of their lives. (Or as a company with employees for that matter.)
The only person I know who is in it for the long haul is Linus Torvald. I thought maybe Marc Andreessen would have stayed at Netscape/Firefox but he's circling in rarefied air with other venture capitalists.
But I see this not as progress but more of the changing landscape of technology. More "normals" are using technology every day, much much more than the days when the first motherboard reviews were coming out. But in exchange for the larger user base, they are expecting this tech to be more "magic toaster"-ish where it just works and if it doesn't, disposable enough to be readily replaceable. So the majority of the world enjoys these advancements but they really don't want to read about the newest processor eaks out a 7% improvement over the previous model.
The reviews that majority of people read are clickbait ("Newest phone catches fire!") or fanboy stroking ("Kanye loves your phone!"). So this means reviews we've come to expect and appreciate are still niche commodities. It means either someone new has a love of these things and wants to write about them or a company decides to carve into this niche and make it their own. Otherwise, with all the defunct sites or buy-outs from a few conglomerates, Anandtech, like all the others will read the same with just different mastheads.
EDIT: I feel the same about io9 and Lifehacker. Gawker made the decision, probably for monetary reasons, to merge all the writing pools together. Now you have mediocrity across the board instead of nurturing the success of some.
