These networks, no matter how they work under the hood, are obviously the problem, as they are single points of failure.
Run your own stuff. Most channels will not have enough visitors/viewers to kill a shared webhosting package, so there's no big deal in doing this on your own.
So "the network" in context of sites like Facebook or YouTube is a fancy marketing term for "the website." Peertube servers actually federate, so there is actually a network there.
You don't have to federate. As host, you can host whatever you want (you are of course subject to laws in the country you're hosting in) and censor whatever you want on your server. You can basically do anything you want.
If you host adult content like pornography it is very likely the larger federation will not federate with your server, and for adult content that isn't pornographic in nature it is probably best to require content warnings.
Maybe I'm thinking too easy, but what about self-hosting. Some "all inclusive" hosting with Hugo or whatever static page builder you like.
That should be enough to get your content out to the masses.
Throw in Disqus if you really need to, set up an RSS feed and a newsletter and let's go.
