You're correct and apologies for the confusion. I didn't mean to imply that EE is open source. It is proprietary and source available. I was actually more concerned about the comment that EE is "off-limits" to contributors and wanted to set the record straight.

AFAIK many company employees can quite easily contribute to projects under an OSI approved license, while contributing to projects requiring CLA is generally much harder & requires clearing the given CLA with the legal department.

And I'm afraid contributing to a "source available" project that is not even open source will be even harder.
