How does that work with the multitude of publicly available, popular videos of Nintendo games that are on Youtube? Are those somehow being protected from that, or is it just Nintendo having a particular issue with a GBAtemp channel?
Anything that is already uploaded to YouTube is basically grandfathered into the program.
Any other channel that uploads anything new, runs the risk of having a strike down, due to the relatively new policy.
Don't get me wrong, it's not like Nintendo is immediately going to see the video 2 minutes after we upload it and take it down, especially considering how much content is uploaded to YouTube, but it's a matter of the long run of Nintendo's new youtubers policy.
Not to mention, a lot of those videos that get uploaded now aren't always going to be taken down, it also means if anyone makes any money off those videos via YouTube monetization, Nintendo will let you keep it up if you cut them a bit of the profit of that monetization.
I could be screwing up the explanation a bit, but that's the basic gist of it.
