Youtube as others noted isnt as evil as reddit or others, but peertube could be a good augmentation to youtube which stores loads of data. However Internet Archive stores alot of data as does Wikipedia don’t know how though. You could also pay per video, one cent per video no subscription just own what you buy. Or you could find way of compressing video data consumption files like is done with png and obsidian files. Or merge ads with content but with a marketplace anyone who wants to sale a product can post to specilized instants for sales and only those who want to buy would be subscribed to for profit instances.
