Well let me just say, "Ha! Ha!"
40 years of demanding companies only lock into Oracle tech and now you're whining like a bunch of toddelrs because it might mean you won't get a look in now you're bidding for deals? Excuse me while I adopt a Nelson Munz pose and say "Ha! Ha!".
I've suffered at the hands of Oracle's nasty severe audits where they literally checked every executing process from their software to see what charges could be added to the bill, I hope they award the whole damn contract to Bezos and Co, stuff it right up Larry and his dying-on-its-arse company.
