Some day we'll lose this ability and it'll be a sad day for HN. Feels like a special trick we've got to enjoy while we can. Nice submission OP - I learned something.
Who actually pays for legacy media anymore?
Other options: a) Just have subscribers, and make do with whatever those proceeds are. b) Give subscribers access to some freemium articles. c) Give subscribers early-bird access to articles. Free access to others later (say, +1 day or so). d) Give non-subscribers 1..3 freebie articles, then paywall.
To name a few. But no: paywall everything, monetize to the last bit. Sign of the times, or indication of this news outlet's priorities / ethics?
