I don’t know who he is but it would be trivial to fight them. He will win.
You have to understand, that Nintendo taking down videos is NOT them ‘protecting copyright’, it’s actually censorship. Let’s say they just happen to take down a bunch of let’s plays where the let’s players criticize some game mechanics rather harshly. “Oh man the paint gun is sooo broken this game sucks ass bluh bluh”. Put that in front of any sane judge and they’ll throw it out of court. Censorship, at least in the USA, is still not legal.
And even if someone doesn’t criticize the game, they could say there was criticism and that they’re being censored. It’s all about freedom of media, something the USA still currently protects against. (I don’t know about other countries laws, btw, so if you live in Europe, all of this may just be wrong entirely.)
There’s also the argument for transformative works. Do people care what game Pewds or Cr1tical plays? No, they watch to see those two’s personalities in action, not what specific games they play. By let’s playing something, you are transforming it and making it about you. It’s like Jon Oliver/Stewart, people watch their videos because they are funny, and the issues they tackle are really just incidental.
There’s more, though. You have to understand how the youtube copyright system is currently set up. Unless you’re uploading a full movie, or you’re uploading OST’s of games (Anyone who uploads a fire emblem OST, btw, IS liable to be sued, keep that in mind) you pretty much cannot lose a copyright dispute. There have been millions of takedown notices issued over the last few years, and to date there have been zero lawsuits by corporations and companies. Zero. The problem is, most people get so intimidated by the glaring red notices that they don’t do any research to find out that the system is finally set up entirely in the favor of the uploader now, and they just stop once they get a takedown notice and give up.
In fact, I dare say youtube’s copyright rebuttal system is perfect now. Well, the only flaw is that you can still suffer a 29+29+14 day takedown time before it returns, that should be dropped to 7+7 days, tops. Going two months unmonetized on a video is awful, and what’s worse is that if you don’t immediately unlist the video, some instances will result in YOUR video’s ad income going to the person who filed the claim, and you cannot get that income back. So if your awesome new viral video of you speedrunning the newest Mario game gets taken down by Nintendo, they can steal your millions of views worth of ad revenue, and by the time you finally get full rights back, you have lost that revenue. So always immediately unlist any video for the duration of the copyright process. If you leave it up, you incentivize them to move slowly if this was one of those instances where they are leeching your ad revenue.
Anyway TL:DR, Youtube’s current system is perfect, minus the 30 days and another 30 days and two weeks of time maximum to process video takedowns. That’s dumb. If it was two weeks tops, it would be literally fair and perfect.
