From my years of experience with content, big tech, marketing and censorship (only in the past 4 years) - there’s no magic solution. 
My strategy is omni-presence - being on as many channels as possible, and being prepared with redundancies for the day they close one channel for you. 

Two platforms I would consider if I were you: Spotify and Substack. 
Both have video, both have decent discovery mechanisms for new audiences. They’re not YouTube - but they’re opening you up to more audiences. 
Rumble was mentioned here but I don’t think rumble or Odysee have the discovery of newcomers that YouTube has. I’m on rumble too. 

Happy to chat more about it (offline or online) if you wish! Good luck! 😍💜
