I agree TED is a bit of a nexus for it. In my circles I see a sort of backlash (or maybe, better, buyer's remorse) directed at TED being fairly broad, hitting many people who wouldn't read more than a few sentences of Morozov. But then Morozov thrusts a dagger into that wound for a subset of people. For people who
never liked any of that stuff and just think society is going downhill with all this technological nonsense, Morozov has less appeal, because you've already got Nicholas Carr and many other people for that angle.
You mention ideas vs. packaging/motives, but I think I've gotten more skeptical about the style of idea as well. Skepticism of the marketing/book/speaking-tour angle probably plays a role in that, but the ideas increasingly seem sort of fluffy. I like to think TED was better back when I was more positive on it, but I've re-watched a few older talks I recall liking, and they seem to have aged poorly, at least for me. I don't have anything against popularizing science, but I can't find much in the TED archives anymore that reminds me of what I think of as good popularized science, up to the gold standard of a Carl Sagan. It more often reminds me of motivational speakers and self-help gurus, the kinds of ideas you see on a CNN segment or something: new science says [amazing revelation that will change your life]. The Onion parody floating around [1] caricatures some of the rhetorical style pretty well. The style somehow seemed fresh at the time, but looking back on older TED talks now, they seem not all that different from stuff I was already familiar with earlier, a certain genre of lightly science-flavored "idea" stuff that's existed since at least the '70s. Maybe with better production values— some of the '70s stuff seems a lot more embarrassing even now.
