As members of the European Union sign ACTA into something that we should use, it still requires ratification from the European parliament. Many citizens decided to fight against ACTA, unfortunately while these protests are happening, the government signed the treaty anyway.
ACTA can impact the Internet. ACTA may not be as popular as the SOPA/PIPA bills were. The anti-SOPA protests resulted in a positive way. On the other hand, ACTA appears as if the complaints are not being heard. Many people are protesting, and want the government to notice.
At Avaaz.org there is a petition where citizens through European are invited to sign. Its goal is to reach 750,000 signatures, currently the petition is close to the 600,000 mark.
Maybe these governments will sit up and take notice of what their citizens want although, considering all the governments that have already signed ACTA, these protests may not do any good until the EU parliament looks at the treaty, but is not going to happen until this summer.
