Couldn't it be also because of bots/paid-humans writing the same kind of comments and liking them to make them bubble to the top?
There's a reason why youtube comments are echo chambers of "happiness for the video". It's like Reddit, where you are writing comments to pass the hive mind filter. Welcome to modern communal interactions, where having a valid or invalid opinion is bad only because it is different.
On the flip side, for some (usually the same) topics it’s easy to write banal karma-fishing comments sure to rise to the top of the thread. At least HN has a time-decay aspect on those.
YouTube comment section is basically a cesspool of toxic positivity now, with absolutely no informational value at all.
I feel like this has been the case for a couple of years now, where nothing even slightly critical will be surfaced by whatever automated algorithm they are using to filter/boost content.
While objectivity and truth are both good, the way how people phrase things can sometimes come across as quite mean spirited, almost like an attack on someone else. This is probably in part because there absolutely are people online who actually enjoy posting vile comments and hurting others, so many have their guard up. Ergo, more luck can be had when phrasing things constructively or without a tone that might even accidentally appear dismissive.

I'll even go as far as to admit that in my eyes this is for the better. Recently someone from LTT came out as trans and many of the comments initially were just painful to read. Lots of attempts at being as hurtful as possible and just horrible rhetoric, that not only adds nothing to the conversation, but also brings down the mood of everyone. But revisiting the video now, most of the comments are far more civil and the vile things have mostly been purged, reading the comments now doesn't hurt.
It's probably quite hard to find a middle ground between being too aggressive or lax with moderation and the degree of this will vary between different communities - what sentiments are okay, what jokes are acceptable, what rhetoric can be used. My hopes are that Internet and the various popular communities will remain humane, while still allowing for discussions and disagreement about most topics.
I think that HN typically finds a decent balance: people can have disagreements without getting too uncivil and it's kept that way. I remember discussions about WFH and someone who told me to "get cancer and die" got flagged and more or less removed from the discussion, because that didn't contribute anything.
