Some people like to have a high horse to ride in on so as to make them appear better in line with their "outspoken enthusiast" ideologies.
Sometimes it is a Prius, sometimes it is a certain wardrobe or vinyl collection. In your case it appears to be Netflix's streaming service.
Simply because you found it to be a good plank in your soap box platform doesn't change the fact that the original post was spot on with regards to folks rationalization regarding their reasons for pirating content.
The fact that there is a nonzero number of users for Netflix's streaming service proves that's not true.
All that proves is that some people don't value their money as much as others or rather maybe they feel that the righteous entitlement that they are purchasing by remaining within the legal boundaries is worth the money.
