Youtube is some kind of madman playground. I have created YT channel for my daughter's cello teacher, where I uploaded Dmitri Shostakovich "Prelude" played by them.

A few moments later I've received information that this piece is "demonetized" (I wasn't even trying to monetize it) because part of this "song" is a copy of some other "song" owned by someone else. That other "song" was in no way related to the Prelude besides it was also played on two cellos.

I've started some "dispute" process not because I am planning to earn money on this channel, but to somehow stop that idiocy that YT keeps pushing.

If Google is using the same "AI" that was used to compare those movies for the purpose of matching ads with those who does not use ad block, I am really sorry for advertisers, who are paying money for this.
