Monetization is one of the main problem of PeerTube, it's more expensive to make videos than to write threads, and while on YouTube/Odysee/Rumble content creators earn money, on peertube they often need to pay to instance operators to pay for hosting

User experience for peertube is not the best too, while in the most of the Fediverse for instance to connect with other instances a user just needs to follow someone on it, on peertube instance owner needs to add instances to the list to federate their content
