When I was young I played with Kapla with my brother. At around 19 I had my own place to live and I decided to take with me the 6000 planks (unused for many years) we had at the time. I then started making big constructions alone and uploading it on youtube. This is the first video that made ~100k views at the time: https://www.youtube.com/watch?v=tzVcXvCcE5s. I turned on monetization and my channel earned about 30eur/month. I let it run for about 5 or 6 months then turned it off because I didn't need the money at the time and preferred that my viewers see no ads. I kept making kapla constructions. I made deals with citiblocs (another plank company) where they give me free planks and I make videos for them on a separate channel. I then made a deal with Kapla (the company) where they send me 25000 planks and I make videos for them. At one point, kapla asked that I remove (set as unlisted) citiblocs videos and I did because they have been quite generous overall.

Recently I turned on monetization again and it makes in the order of 400-500eur/month. I told my brother who helped me on some videos. To give a few examples, here he does help: https://www.youtube.com/watch?v=W61THELYq48, here he doesn't: https://www.youtube.com/watch?v=hIbsx9PeH84. About ~1/4 of the videos he helps me, it depends. The projects always have been my initiative, I own the planks and I edit and post the videos on youtube.

Today he wants some of the youtube revenue. What he specifically asked for is that I "give" him all de-listed citiblocs videos (with the consent or not of kapla), so he can create his own channel and have the revenue of those. I should mention that we have past disagreements about how to share the equity of a startup I'm trying to create and he left early (but that's another story)

Given the situation I describe, what is the reasonable thing to do? Is it legitimate for him to ask for some of the youtube revenue of my channel?
