I agree with this view, and that Netflix must be quite negatively addictive for some. Following from that, I wonder why we don't see similar articles about Netflix as we do about quitting facebook? It has the same kind of relevance to HN but I can't remember ever engaging in discussion about Netflix addiction here.
It sounds like survivorship bias. Netflix is a passive hobby and Facebook is an active one. The people who discuss on HN are likely to indulge in unproductive discussion. Whereas the people who lurk HN quietly and excessively may be likely to indulge in slothful behaviour.
