Maybe I missed it somewhere. But would someone please clarify whether they are talking about databases or instances? They are not the same thing.

I find it very hard to believe anyone is doing some of the stuff they say here unless the words are being misused.

And I don't care how much junk people decide to consolidate ... why more instances or more databases is better than more tablespaces and schemas (in most situations)? This line of reasoning I don't follow.
