The “ACTA2” reference is a little inside baseball for the US audience–ACTA was a multilateral executive agreement (not a treaty) that would have strengthened copyright around the world. Google opposed ACTA and drummed up astroturf opposition in Europe–which deserves a second look now that major newspapers have confirmed the extent of the Cambridge Analytica-style gaslighting campaign in Europe that Google and Facebook marshaled against the Copyright Directive.
“ACTA2” is a weak attempt to compare the Copyright Directive to ACTA (“ACTA2”, get it?) in hopes of mobilizing Europeans to reject their cultural monuments and embrace American multinational corporations who pry into their most private information and sell it to advertisers. Oh, yeah.
