You just argued that running (100m, marathon, etc) is not competitive, that weightlifting is not competitive, that bowling is not competitive, that target shooting is not competitive. Just achievements.

That's fine, you can humpty-dumpty words all you like, but everyone else thinks that those things can be competitive.

However, note that literally the entire point of the author of the blog post is that he doesn't want to be competitive and does not see his own behaviour as competitive, but rather as collaborating on achievement, so it's super weird that you're snarking on him.
