This seems like overreacting to me. Why all the doom and gloom?
Yes, YouTube's landscape will fundamentally change come January first. Yes, certain content creators will no longer be able to rely on advertising-based revenue or YouTube-hosted community features. But YouTube does not have a monopoly on hosting content. They are simply the largest platform around (which is why they're being regulated by the FTC in the first place).
So please, whatever you do, don't stop making the things that you enjoy creating. We as a community may just have to work a little harder to share our work with one another. I've been in online LEGO circles (especially YouTube) since 2009. That was before AdSense, the "algorithm", the notification bell and all these other features we take for granted nowadays. The community survived just fine back then.
In fact, I would argue that YouTube was a much healthier place without the potential for overnight fame and fortune. So maybe, in the grand scheme of things, this whole YouTube/FTC/COPPA situation will actually push our community in a healthy new direction. We will no longer be able to rely on mega-platforms like YouTube to gain exposure. We will have to do the work ourselves. And I for one can't wait to get started.
