Note that the HN submission's title was changed to "Gumroad’s source is available" after it was screenshotted for this post.
This post also seemed to be thrown off the front page for some reason.
But with this title, the discussion can be drawn towards the question of whether the license would or wouldn’t meet the widely regarded definition of open source, rather than whether it meets each commenter’s own definition of open source, which would be a much less gratifying discussion.
(I've frequently suggested title changes to HN's mod team, I'm pretty familiar with this.)
