I doubt it, it is common practice for us to use personal e-mail addresses for open source contributions (since many of us have pre-existing community involvement before working for Red Hat). And we remain culturally distinct from IBM.

As a side note, really often we get asked to measure our open-source contributions, or get measured by some sort of analysis of a project. It is always an under-estimate because of all the non-redhat.com accounts that we use.
