I believe the correct term is rant since it was a rather humourless and somewhat condescending, thinly-veiled letter of reprimand for BCash detractors.
Someone from the BCash camp gave Rick Falkvinge the green light to write it and put it out there. And I believe that he wrote it as a quite serious, passionate diatribe. It was full of narcissistic hubris and swagger in support of BCash and it's supposed principles. The same kind of crap we hear from Ver and Wright. But it inadvertently showed how much centralized control and influence over BCash and its supporters that they want to enact. Like a fkn cult or something.
It's only when the whole thing backfired and their camp received backlash and derision, that they started walking it back as some sort of "joke" or "prank" or some attempt at satire.
Rick is one of those political figures that deep down might mean well, but has now become so egotistical and full of himself that he truly believes that everything that he writes is awesome and that people are moved by his amazing, eloquent prose. Which is neither amazing nor eloquent.
