When I read the original article it doesn't really feel like the Finnish guy is even an activist. He seems to be just a curious nerd who wrote one article about this topic (who's behind this big site that everyone uses) and about a whole load of completely unrelated and non-activist topics like why did Japan stop building subway lines. Then his blog gained some traction because of the reporting around the FBI threats.
The article is also really appreciative of archive.today. It doesn't feel like a hit piece at all.
