The best solution is what the Indieweb folks called POSSE: Publish on your Own Site , Syndicate Elsewhere:
For instance, I might publish a clip on my own site first, then mirror it to places like YouTube, TikTok and Reddit so more people find it. Or post an article on my own site first, then repost it on Medium and Substack (with a canonical saying my own version is the original if possible).
That way you're not tied to a specific platform, and can just find another place to share/post your work if any of them go to hell.
