I want to know the answer to the following question:
Which term is criticized as vague?
All the background I'm provided with is that "Many detractors think this term specially serves the doctrinal agenda of parties opposing reform in the public interest or otherwise abusing related legislations; and that it disallows intelligent discussion about specific and often unrelated aspects of copyright, patents, trademarks, etc.". Is that enough to answer the question?
Answer: no
