“actually”, no it doesn’t. that’s the old youtube logic. now youtube actively buries any kind of engagement like comments or liking, it’s not useful. youtube does not care about who is leaving comments or not, and leaving comments itself is highly susceptible to bots.
again, all youtube cares about is about watch time, and if you share something with someone else as that leads to more watch time. people arguing in the comments has zero relevance on how many ads people see.
