The author make it very clear that he understands the problem Anubis is attempting to solve. His issue is that the chosen approach doesn't solve that problem; it just inhibits access to humans, particularly those with limited access to compute resources.

That's the opposite of being dismissive. The author has taken the time to deeply understand both the problem and the proposed solution, and has taken the time to construct a well-researched and well-considered argument.
