For some reason, unlike most other commenters, yours doesn’t present the downvote button. I thought this might be a privilege of very high karma like other downvote-missing commenters i see sparsely lower down, but your karma is lower than mine and I get downvoted frequently enough. I’d like to understand HN’s community management functions better.

Could it just be the comment is too old? IIRC, comments that are over ~24h old can no longer be downvoted.

That’s probably it, thank you!
