I'm glad you brought this up. This was the exact question I had a few years ago, when I began developing my idea for a solution.
What I considered to be the best approach is to break apart the idea of hosting content and sharing content with your audience in the same place. If you can share in one place and host in another, then switching content hosts ceases to be a problem; You can transfer your content to a different host while preserving the space in which you share, losing no audience or traction in the process.
I'm currently in the process of launching this platform, called MyNexus. If you'd like to learn more, or know anyone searching for a solution to these problems, my email is yaniv@mynexus.io.
That's where the business model comes in. To focus on being a positive tool for content creators, I decided to charge them a monthly fee to have their page on the platform. And I maintain absolutely no other means of revenue. The entirely of the business depends on creators finding it a useful, reliable, and trustworthy tool that is worth their money.
I know that doesn't strictly forbid banning certain content, but without the pressure of having to satisfy advertisers, etc., I don't expect to need to ban content. The only exception that comes to mind would be restricting certain content in order to comply with laws.
Please do follow up with any questions or concerns you have. My goal is to be transparent and to build trust, so I'm happy to address them.
