I love this part: 3. Avoid Two-Way Engagement Reviewing an unsolicited patch from a contributor in a sanctioned region should generally be fine, but actively engaging them to better understand their issue, diagnose the problem, or help improve a patch or modify code would likely cross the line. If the contributor is linked to a sanctioned entity or region, in general, it is best to keep communications strictly one-way. If a patch is received and you improve it and submit it upstream, that should be fine, but going back and forth in communications with the SDN developer likely would not.
