What you're stating is a gross generalization and untrue in a literal sense (probably easy to realize if you remember how things were a decade ago).

While Y!J and Y!Inc are separate entities, the former does borrow/use technology from the former and some of the Y!J services use Y!Inc servers and/or services maintained by Y!Inc.

Y!J user ids are completely separate from Y!Inc though (Y!Inc ids are shared through out the Y! locales).

It's been almost a decade since I was at Y!J, but from what I understand Y!J does continue to leverage the Y!Inc relationship for services and servers.

Additionally, simply stating that old technology is the reason for a security breach could be a red herring, it isn't always the age of the technology but how it is implemented.
