They are in a difficult position because the entire point of their DNS resolver is that it blocks malicious sites (malware, phishing, etc.). Very easy for Sony to say, why can't they add piracy to the list? They "refuse to alter or lie to you" in their DNS responses - how would a malware block be lying if those other blocks are not?
But even malware filter is supposed to cut malware, not pirated content. Cutting piracy while saying that you cut malware is def lying because pirated resources might not provide anything malicious for the end user.
