This is an interesting prospect; you've basically traded in the idea of writing an anomaly with writing an ethical dilemma. The article itself is structurally sound, the pace is well metered. Even though a factory that produces borscht is pretty mundane itself that obviously isn't the point of the article.
The larger issue, for me, is the dialogue between the EthCom members. I've never been super keen on members of a numbered committee addressing themselves and each other by those numbers (the Overseers get a bit of a pass on this because of the nature of their position). It might be headcanon but I don't see the Ethics Committee as being too much different than other panels within the Foundation, and definitely not deserving of that kind of crypticism. A minor complaint, but one worth mentioning either way.
The larger issue here for me is that this is pretty well trodden ground. "Maintain normalcy" or "protect the population" isn't something new, and since all of the arguments being made by the committee members are essentially just variations on this ("we could've helped before but didn't, and thousands died", "it's not our job to interfere", etc), the entire dialogue comes across feeling a little bland.
What would've been really interesting here is a discussion about, if the Foundation is unwilling to aid in the humanitarian efforts in Leningrad, then what is the purpose of the Foundation? If their mission statement includes the word "protect", but they are unwilling to do something for the obvious benefit of mankind, then can they really claim to be on the same side as mankind? Especially in this case, where something like this could be pretty easily accomplished in a way that wouldn't pull back the veil or what have you.
I guess what I'm saying here is that my singular complaint is the missed opportunity. Not that what's there is bad; on the contrary, I plan on upvoting this article. What's here could have been more, and that's definitely something to think about moving forward. Really good work otherwise, though.
