If by Oracle you mean heavily modified version of mysql, then yes. Or if you mean Java, then yes.

But if you mean any Oracle technologies that need to be licensed, then no.

I don't know, but based on your statement, I'd guess that they each probably have a few licenses for enterprise-grade apps. I don't think that changes the analysis that the market is moving on from what Oracle is selling.

Google and Apple? Are you sure about this?
