Well, it's a look at it from the perspective of someone who creates games.
Interesting bit of confusion in his thinking:
And anecdotally, people who pirate your game probably wouldn't have bought it anyway.
Many of the games that shaped who I am today were pirated, and since then I have bought some of them several times over as they are re-released on various platforms – but without that link to the past I never would have known about them in the first place, and likely wouldn't have bought them now.
On the one hand, he says most who pirate don't end up buying the game. On the other, his own anecdotal evidence shows the opposite.
Maybe it points out the dilemma of authors, where they have to decide to either put up DRM roadblocks, albeit inevitably temporary ones, or instead just let it roam free from the get-go and hope for the best.
