Huh? If some random guy didn't do something to make himself popular (considering he's really smart, if he didn't make Linux he would have still probably done something else massive) how would he be a troll?

Your comment makes no sense... considering the only reason you/hn/whoever even reads his posts is because he's the Linux guy. If he wasn't nobody would even read it, and you can't troll nothing lol.

How is he trolling in this instance?

Shipping goes a long way.
