That's all? Should have been $5. /mysterd impression
And here is the heart of the argument, the position that explains why it started in the first place. A fundamental disagreement in the battle between copyright and free speech.
Take-down claims get submitted all the time, that is NOT why I mentioned the controversy. I mentioned it because of the e-mails, the threatening, bullying, dickish e-mails. I was not one of those people who had a hissy fit over the takedown (as there's an argument there), but the e-mails did piss me off. Lying about e-mails you sent, threatening lawsuits in attempts to bully, is NOT acceptable, I don't give a

WHO you are. TB said nothing in those e-mails that deserved that kind of response. It's plain arrogance by the devs.
Remember, they told him to take down his ENTIRE Twitter and YouTube channel. Not JUST the video (it was already gone). It was PERSONAL. And that is indefensible.
As for how you feel about "fair use", you're half-right. I don't believe that someone has the RIGHT to monetize someone else's work (though if the creator has 0 complaints, they can), but I believe they have the right to use it under the conditions of fair use. YouTube has recently addressed that by denying ad money to people like Angry Joe once their system's content checker flags it for copyrighted material. It doesn't take videos down, just denies money. But these devs went out of their way to remove the video altogether.
Fair use ALSO extends to include parody, Fox. It's why Abridged Series get away with it. And that's why TB is covered by it.
