As someone who has to deal with COPPA as part of my job, I guarantee you there are going to be random unforseen challenges and changes no one's really thought of yet. COPPA is so poorly thought out, there's a lot of "wink, wink, nudge nudge" that has to go on to even TRY and make it work in the real world. In reality, most websites simply ban or completely turn off a lot of features on their site to any user under 13, because it's just too much a PITA to deal with. Which of course leads most underage kids to lie about their age, making the whole thing pointless anyway. Not to mention all the parents that actually get mad their kids can't enjoy all the features a site has to offer, if the kid makes a "mistake" and is truthful about his age. We are literally teaching kids to lie, and some parents are encouraging it. And I can't blame them.
Considering YT just paid a big fine for violating COPPA, you can bet they're probably going to error on the side of being too strict on their creators. I didn't watch the video above, but I've seen more than enough others on this subject recently. I'm not sure some of you guys really understand what happens to a channel that's marked for kids. And that matters, because there are quite a few channels that aren't aimed at kids per se, but are very kid friendly. How is YT going to handle that? Legos, Pokemon, MTG, video games, animated movies/cartoons - there's just a ton of shit out there for adults, that also appeals to kids. How's YT going to categorize all this? Because they plan to use machine learning (laugh) to make their own judgments on what age videos are aimed at, regardless of what the creators say. The FTC has tried to issue guidelines on content delineation, but have probably left people even more confused.
While it's certainly not the end of YT, it will have an effect. But don't Chicken Little over the "$42k" fine - that's being severely overblown, and is actually based upon your income. YT marking your channel as for kids, or just outright canning it, is the real concern.
About the only good thing I can say about COPPA is, at least it's not GDPR. That shit is even more retarded, if possible.
