True, but if YT doesn't provide reliable ad revenue there's less reason to only put your content on YouTube. And with general unhappiness with the platform comes a desire for having at least a backup plan, so why not start posting in multiple locations now?

If by "backup plan", you mean your videos being accessible, sure. But usually, when people talk about diversifying, they are talking about revenue. In this case, PeerTube isn't really bringing revenue so I'm not sure it helps much. What would help is getting a Patreon or streaming on Twitch. Those are different sources of income, PeerTube isn't really unless you get hit like Blender did.
