Ultimately, people seem to be demanding that EVERYONE suddenly reveal all this rampant corruption that supposedly exists, and, judging by some comments I've read in this thread, it appears that this corruption might be very Eurocentric (the GMAs are, yes?), and thus something that the American sites don't really have that much to say about.
This is what should have happened: A reasonable number of outlets officially weighed in, and on Twitter people agreed it was serious.
Look at Rock Paper Shotgun. A contributor wrote about the topic somewhat seriously on his personal blog, but RPS's only official response was to mock ethical concerns and trot out the tired "we at RPS all have superhuman wills and are never swayed by anything."
In the case of RPS they said they won't address the issue because they cover games and not games journalism - then they went ahead and DID address the issue, just to mock it.
Asking for more than that is not asking for too much.
