You are talking about hypothetical situations in the organization with around 2694 maintainers. What I find interesting, is that no one in this thread thought it would be good to check if these 11 already contributed something harmful. Instead, it’s just “good, we prevented a bad thing”.
Anyway, your extreme take “ban all Russians because what if” goes much further than what happened in reality (“ban Russians working for companies under sanctions”): https://social.kernel.org/objects/860ef93c-229b-4070-8ee6-cb80d1f51337
I’d rather see Fairphone expand.
