Danzo was the one to contact obito. Itachi didn't have the MS until shisui's death. Two uchiha that had MS were Shisui and Fugaku both with comparable strength and far outmatched Itachi but Shisui was defeated by Danzo. Don't think that an entire uchiha clan has more than 100 shinobi genin-anbu and less had mature sharingans. Despite having sharingans the uchiha here are outnumbered and can still be defeated since a sharingan means nothing against even a byakugan and thats one clan amongs many with almost a similar population to the uchiha. The sharingan is mainly specialized in genjutsu and helps in deciphering jutsu and increase reflex in taijutsu but a hyuga is almost a best counter to all that.
