If you're publishing on your own website instead of a social media platform, your new Kings are your domain registrar, registry operator and ultimately ICAN itself, your hosting provider, Let's Encrypt, all the email providers you need to be able to deliver to (notably Microsoft and Google), and probably also your payments provider.
Despite what people say, the internet is not decentralized, and it's no longer possible to build a site that isn't in anybody else's kingdom.
This is mostly a good thing, if this wasn't true, somebody would have set up a site that was a safe haven for child porn, and there'd be nothing that anybody could ever do about it.
Do people say this? I’ve never heard anyone outside of web3 land say this.
IIRC it’s one of the big disappointments of the internet that is evolved in such a centralized way.
But also you can deploy a website which doesn’t rely on ICANN or a hosting provider, lets encrypt, email, or any of that.
Your only “king” would be an ISP (which you could also run yourself, if you were so inclined)
It wouldn’t be an easily accessible castle, but it’d be yours.
