2. The other, Disney and Sony works out a deal where Disney get a copy of the Spider-man film license and Sony holds on to there license. So there will be two Spider-man universes one release by Disney and the other by Sony. With every major Spider-man film Sony gets ~5% and every Spider-man cameo Sony will get ~1%. I believe this to be fair as it allows Sony to get free money via the Spider-man license and it allows Disney to use Spider-man for their MCU.
