Protection is ok. Whenever a question gathers that much publicity there are many who are not aware of how the site works and try commenting by answering the question with a comment. Which is unwanted on SO/SE. It doesn't prevent people from commenting, it doesn't take the question away, it doesn't prevent established users from giving a better answer, so I feel that's not as drastic as migration or deletion.
