This is just such a strange thing to point out when the more relevant thing is that the comment itself does NOT display the number of likes even though that USED TO BE how the site worked because the people who maintain it decided doing so was actually a bad idea and actively removed the display of display of like counts one day, and while some people momentarily whined pretty much no one does anymore as it absolutely did turn out to be better to not have that mental clutter in the user interface as, in practice, it was irrelevant information for how people use the website.
Karma and voting are ruining Hacker News as well, just not as quickly because the algorithms here are not as aggressively tuned to maximize engagement.
