Okay, it's not censorship if I'm editing your graffiti on my wall. Yes, Youtube invites content creators to post content on their platform, but at the end of they day, it's
their platform, and they decide what is and is not appropriate use. In effect, your free speech rights are captivated by the private property rights and speech rights of the provider. Also, you signed the terms of use when you created the Youtube account. If you really want to create a Let's Play over which you have complete editorial control, I recommend you build and run your
own server.
Now I agree that it's regrettable that Youtube's algorithm and staffing isn't quite aware enough to understand satire, or metaphor, or even fantasy, but at the end of the day, the current obsession with remaining politically above reproach is the inevitable result of clickbait, soundbyte media. My only recommendation to regular citizens is this: Don't be part of the problem: Don't click on clickbait.
