Everyone I know that reads it has said 'I used to read Adbusters until...' they realized it was condescending/ hysterical/adolescent posing.
I've never seen Adbusters criticize the scandal-plagued Canadian government in any way, which would be like shooting fish in a barrel. I'm pretty sure Adbusters is sponsored by the Canadian government in some way, so it's not much of a stretch to say it's just propaganda you're mistaking for 'radical, independent thinking' or whatever.
It's like some scare campaign to make us think we need our crony, corrupt government to protect us from evil companies who are out to, you know, MAKE MONEY!! Like they're saving us from american corporations marching across the border to round us up and imprison us in Wal-Marts, force-feed us McDonalds and make us watch Baywatch for the rest of our lives.
