The similar number of downvotes may be explained because many users (i.e. me) don't like to downvote grey comments (unless they are very offensive or extremely wrong).
Moreover, I sometimes upvote grey comments that I don't like because they are too light grey (unless they are offensive or very wrong). I guess I'm not the only one. So this may explain that some comments stabilize in the same tone of grey.
