I have seen at least two major content creators that speak about the war in Ukraine, with bias to Ukraine to be honest, complaining about their content being considered "copyrighted", "unsuitable" and either banned, de-monetised or both.
One of the guys tried simply reading a nursery rhyme - this is a video of someone simply reading a popular poem for 5 minutes - and got it de-monetised / banned. Another guy got a "copyright infringement" for a video in which he shows his webpage and speaks about the content he creates. No music in the background, no videos not images other than generic pictures of stuff.
If anyone in youtube is reading this, please know that your system is being used to stop freedom of speech and stealing money.
