Those counters are a bad compromise to begin with, because they are a substitute for a well thought through reply/comment, everything that needs to be reported is outside this scope anyway (minus the people that abuse the report function).
Of course i do give a quick thumbs up if i like the content to somehow show that i would like to see more of that, otoh i am sure creators would prefer to read an actual comment that expresses it more than that, but in both cases there is probably nothing to argue.
If i however disagree with the content or just don't like the horrible presentation or a single issue out of all those talked about don't seem to line up with me, i would be required to write a comment to explain what it is
to be fair and that's where that dilemma starts, i would need to take effort for something i don't like, criticize someone publicly although they put hours of work into it or it is just a result of my own misunderstanding. The dislike button seems to solve these problems, but just increases confusion.
IMHO trying to extrapolate specific information out of those counters is a mistake most of the time. E.g. a video with factual errors but high viewership approval would have a misleading counter as would a video stating truths but with a high disapproval rate because people do not like the facts presented or think the video should not be in their feed. Wouldn't be a problem if there was no such counter and people would actually need to write a comment and someone would read them. (I'm naive
)
But youtube is an attention economy, not all devices are suitable to do more than a like or dislike (i.e. TV) and any metric was put there for advertisers and creators to have something to argue about or somehow estimate a value from it. Which would work until it is weaponized, faked or misjudged; and it is always just a question of time if something is weaponized, faked or misjudged. Even comments...
If youtube decides to remove it i don't see a big harm to the community, the problematic judgment derived from it was probably ill-fated anyway. Because people that correctly understand the meaning of their approval rating will eventually "self-correct" and produce upcoming videos in a way that works for them - or they don't give a sh*t if it works for them too, but hiding the counter will not attract more viewers.
