I am intimately familiar with the mechanism, it's not super advanced. Every time you like/dislike a video it is added to your list of liked/disliked videos and your ID is added to the video's liked/disliked tables.
If a video is flagged as having a suspicious amount of votes then a simple script which examines the viewer's history against their vote is run to weed out possible fake accounts... so when 10,000 people come in from a website and see a video they don't watch and down-vote it those votes will potentially get removed.
It's a really simple, straight-forward, process actually designed to fight what Youtube viewed as theft from them by creating fake views and reactions.
This is literally what I spent many years doing for a living.
If 10,000 people go into youtube from a website, and give a video up votes, will those 10,000 votes disappear? What is the point of a video going viral, or usage of influencers? Youtube has algos to prevent fake views or paid views because it impacts their revenue. Advertisers paid for certain amount of views, and they do not care about thumb up or down.
There is no limit on engagement for votes to be counted - people can down vote a video within 5 seconds or less if they find it immediately offensive.
All of these votes were manually removed by youtube.
That's where your wrong, Google relies on the dislike/like ratio as well as the view/like ratio for placement within YouTube's search results so if a video is being falsely upvoted or downvoted it causes issues. This is why Youtubers frequently ask people to like their videos - it feeds the algorithm... more likes = more views = more money.
So I did a quick check online, and the consensus matches my experience. Down vote does nothing to the algos, ads sales, or any other digital marketing. It is there so the content provider knows what their audience likes and don't likes.

Keep doing your internet research, I'll stick to the code I fucking audited.
