When taking a broad longterm view, clearly Peertube and/or other video hosting and sharing alternatives to Youtube are the most strategically important since as bad as centralization/enclosure of the commons is for various mediums of online communities, the process is wholely complete in a good chunk of the world for informational videos with Youtube utterly dominating.

It is easy to underestimate how powerful of a fulcrum Youtube is for leveraging manipulation and control.

I have no idea if Peertube needs development help (I assume they likely do) and I am not sure what specifically the kinds of things they need help with are, so I say this more as a general observation.
