Yeah, but - google IS the corporate master of google, and they've had zero problem in the past with linking to you-name-it stuff - even google hit-pieces that say they are evil.
No, I believe that there's just no corroborating stuff out there, goog always finds it if there is (and usually several other sides to an argument, and many debunkers) and it got to the 'net at all. They even fully sweep my site ~ once a day, good thing I'm not paying for that bandwidth(!).
But...nothing. Just the one article on each topic, the same one ZH was sourcing from, and zero others. I've never seen that, ever. Usually you'll see half a dozen at least, even if 5 of the six just copy-pasted from the first one. That's just outright weird.
I could see suppression of the Iran one - except it doesn't really need it, turns out it's a quote from an Iranian boat captain, not anything official/for-real. Just some guy boasting. The Russian market thing though - now that really affected a lot of people, yet nothing? Didn't you know there are a literal crap-ton of hackers in Russia who don't have a bit of trouble with censorship, or doing their best to poke sticks at their government? Yet nothing from them at all. That's just too weird.
Of course, putting 1 and 1 together, maybe the hackers are the cause of that. But it wouldn't be all of 'em, just a few, and the rest would be babbling joyously - but they aren't. Just making my old analyst neck hairs stand on end.
