Sorry, not picking on you. Just catching a flaw in the thread...
To recap:
There were a couple of articles over the past 9-12 months talking about how highstreet stores disliked digital distribution.
There's been a handful of games that haven't shown up on Steam until very late, if ever (Brink, Space Marine, etc).
Some guy on Facepunch posts that he thinks that Game are to blame for these absences on Steam. He uses hand waving and reference to these old articles, plus the absence of games on Steam, as evidence.
A guy allegedly from Game denies it on Facepunch, and Game denies it officially to the games press.
Various sites quote, requote and paraphrase this Facepunch poster as if what he says is true without any further research or evidence.
Said guy on Facepunch has yet to provide any hard evidence beyond conjecture. Crowds don't care, though, and pile on Game anyhow.
Does Game deserve it? Probably.
Is Game actually responsible? We don't know; there's a distinct lack of hard evidence.
