Seems to me this is just PLR content (private label rights) packaged as something more "special." Nothing innovative about that and there are tons of niche vendors who've been delivering this type of stock content product for a long time. Long-form, short-form, ebooks, videos, social - you can get it all with various types of licenses that allow you to address the issues around duplicate content. The price tag listed here is crazy high in comparison to other vendors.
