Claiming Adbusters speaks for Occupy movements worldwide is like claiming Rush Limbaugh speaks for all conservatives in the US.
While Adbusters (in concert with Workhouse) may have provided a spark to ignite OWS, I see no evidence that OWS, other US Occupy movements, or other Occupy movements worldwide have completely adopted Adbusters' agenda. I see no evidence that Occupy movements look to Adbusters as their primary media outlet/spokesperson. Quite the opposite, if you look at occupywallst.org, there is precious little mention of Adbusters outside of the site's forums - where Adbusters is frequently ridiculed.
Here's what OWS actually says about their origins:
Occupy Wall Street is a people-powered movement that began on September 17, 2011 in Liberty Square in Manhattan’s Financial District, and has spread to over 100 cities in the United States and actions in over 1,500 cities globally. #ows is fighting back against the corrosive power of major banks and multinational corporations over the democratic process, and the role of Wall Street in creating an economic collapse that has caused the greatest recession in generations. The movement is inspired by popular uprisings in Egypt and Tunisia, and aims to fight back against the richest 1% of people that are writing the rules of an unfair global economy that is foreclosing on our future.
There seems to be no mention of Adbusters.
"Occupy folks" aren't some kinda monolithic group subscribing to a rigid ideological agenda with a single publication acting as their Pravda. You really should open your mind to the idea that many (if not most) of the movements have matured beyond the radical positions Adbusters promotes. You also might want to consider the possibility that the US government's treatment of large financial institutions following the crisis is an affront to capitalist ideals, and is something that *should* be protested.
