Dunno about the website or corp, but the occupy wall st movement was/is true. Happened right after 2008 stock market crash and people camped out on Wall Street in protest of bailing out the banks.
Carried over to Europe too, I remember the camps and protests in many cities' financial districts.
One can make the argument that trump was elected because of OWS knock-on effects...
I would make the correction that the protest movement was not left wing. I think he’s trying to take credit for his favorite team. TARP was opposed by 80% of Americans. It passed legislation anyway. I think there’s a good lesson to be learned in how performative and inconsequential the electoral process is.
