Those people who think this is some sort of enormously evil event that will kill BerkeleyDB because the AGPL is the evilest most restrictive free software license ever should probably read Section 13 here http://www.gnu.org/licenses/agpl.html
This pretty much only affects you if you are running some weird internal forked version that has upstream merged into it regularly. I don't get the impression that this is a common situation for BDB users.
(Although since Oracle did it it's probably inherently evil anyway of course.)
You are absolutely right about the license, but I think you're confusing Oracle with Google. Oracle aren't evil, they just want your money. It's Google that wants to know everything about your life so that it can give you an IV line of ads. Google - evil, Oracle - just greedy :)
