If governments can censor for a "good" purpose, they can also censor for a "bad" one. For example, the laws and technology that allow you to interrupt access to a piracy website could be used to censor any controversial content (note that many positive advances in society, such as women's voting rights, were controversial when first discussed).

So, strong enforcement of intellectual property laws means problems to... free speech and society's progress, if that involves filtering or censoring content on the internet.
