YouTube and Maps are the two most problematic platforms to get away from. Because of the content, not the tech, obviously. Still we gonna start somewhere. For the maps there's OpenStreetMaps and the Organic Maps app. For YouTube I would start with something like NewPipe to stream from multiple sources, one being something like nostr / blossom / podcast3. 0 with video. Then offering creators a simple migration from YouTube to a new open storage / video distribution channel where they can be zapped.
