This is a plain attack on Amazon, which Oracle now sees as a competitor, that will hit customers in the crossfire. I guess Oracle expects customers will simply move to Azure, since retooling ops might be easier than rebuilding solutions on other databases.
It will yet again hurt their image though; they've been hated by geeks for ages, but they are increasingly unpopular even among executives. How long can you do business with people who openly despise you?
I would guess that Oracle isn't expecting their customers to love from AWS to Azure. They are expecting they move to Oracle Cloud. I didn't see any mention of that in the original article but I wouldn't doubt those rules either didn't apply or could be bypassed by your friendly Oracle sales person if you wanted to get a taste of the Oracle Cloud.
Azure has always been charged at "1 core = 1 Oracle Processor" so this new scheme only harmonizes licensing on Azure and AWS. It's still double of on-premise pricing.
