Initially the adoption process went silently, as in other places, like the US. There were a few mentions in some geek media, but 99.9% of the society never heard of ACTA (not to mention having an opinion on it).
But then we had the explosion in Poland, with street protests and mainstream media headlines and loud public debate, so no wonder that the Polish PM eventually turned 180 degrees.
And in parallel, street protests started popping up allover Europe, the EU Parliament rapporteur for ACTA resigned in protest, and now we have a case in front of the European Court of Justice.
Right now I'd say we have like 2/3 probability, that Europe will kill ACTA.
They already blew it with the Data Retention Directive[1] - what makes you think that they'll bend on this?
