"Oracle has been fighting to overturn a stipulation in the DoD's request for proposal that states one lucky contractor would have to provide all parts of the deal. Chiefly, Oracle – let's make that clear, Oracle – thinks locking an agency into a single legacy vendor is a bad idea in terms of innovation and security. Secretly, we think, Oracle doesn't want to risk losing it all to Microsoft or Amazon, so in all, Oracle thinks JEDI is a bad idea for Oracle.Oracle's JEDI mind-meld doesn't work on Uncle Sam's auditors: These are not the govt droids you are looking for | The Register
Oracle and others also complained that, because JEDI is such a massive project, the one-vendor stipulation means that only huge companies, such as Amazon and Microsoft, can fill it, whereas if it were broken up Oracle would have a fighting chance over the pieces. Oracle had also argued that AWS may have had a hand in crafting the requirement, creating a conflict of interest.
Both arguments were shot down by the GAO on Wednesday."
