As is usual for TGP, the weird anger toward anybody on YouTube makes you miss the point. His point is that the YouTube system is broken and it makes it nearly impossible to play a clip of any popular for fair use purposes. Even for a video that is strictly created to be educational.
If you created a 30 minute educational video about different types of harmonies, for example, and then put in a few 15 second clips of popular songs to use as examples, your entire video will get demonetized. So all of the revenue generated by your work goes to a record label even if that portion of the video is like 1 or 2% of the content of the video.
If you don't understand why this is a bad thing for music education and music appreciation in general, I don't know what to tell you.
And here is the crux as to WHY it SHOULD be demonetized: because without those CLIPS, Beato's videos would get MINIMAL VIEWS. He complains about that all the time too.
He knows that his most watched (read: lucrative) videos involve music that other people wrote. So, why shouldn't those people be compensated? It's THEIR music!
Fair Use was never intended for people to make money from things that don't belong to them. It was created for people who EDUCATE others, basically as volunteers. There's a reason you can't watch full movies on YouTube, or SNL episodes, etc. No matter how 'educational' it is, people like Beato are looking to make money on something they don't own rights to.
Beato is an ENTERTAINER, and there's nothing wrong with that. Almost everybody on YouTube, after all.
Put it this way; if he didn't use ANY copyrighted materials, would he have the views and subs he does?
Case closed on this drama-machine nobody and his YouTube 'empire of dirt'. Without other people's material, he literally would have a 50k sub total. Just like every OTHER 'real' YouTube music educator. But he doesn't WANNA be a small fish, he's RICK BEATO, don'tchaknow?
A real SOMEBODY!
