I cannot judge the merit of the paper itself, but Climate Healers seem to be a vegan focused non-profit. So they could be arguing against animal agriculture for other reasons than climate change. Which can be valid reasons as well.
I don’t know about the specifics of the ban described in the description and I am glad that you try to offer an alternative to the established communities. The more the merrier.
My opinion: Figuring monetization out while keeping most of your audience happy will be the most important step to be a viable alternative to YouTube. Big YouTubers like LinusTechTips, Corridor Digital or something like Nebula already have their own service, because it is worth it to have fewer people pay more. Sadly everyone of them develops their own solution which are not interoperable. Are you in the talks with anyone to migrate to PeerTube backend? I think this would be such a gamechanger.
