How long has it been this way?

[eroM]

eg videos with "relaxing" music are not a good fit; people "listening" to them are not "watching" them, and they are not looking for a solution to a problem, so they are not likely to provide much of a clickthrough rate for the creator to earn money nor not much of a return to the advertiser who pays for any clicks that happen
etc

This hurts so much but it is so true

eh, I remember I had seen this somewhere...

Not answering for Youtube's state directly, but it might reflect the "platform's" level.

The Guardian in 2009 described users' comments on YouTube as:[391]

Juvenile, aggressive, misspelled, sexist, homophobic, swinging from raging at the contents of a video to providing a pointlessly detailed description followed by a LOL, YouTube comments are a hotbed of infantile debate and unashamed ignorance – with the occasional burst of wit shining through.
