That's fair which is why I'm asking if a piece of code has been published supporting the claim of down-ranking.
If it hasn't the answer is to very carefully qualify the statement "Analysis of Twitter algorithm reveals Twitter down-ranks tweets about Ukraine" rather than treating the people who question it as heretics.
I agree. It shows the danger of selectively releasing code and how the "Twitter open-sources algorithm" rhetoric is deeply misleading, at best. Hopefully, any misplaced analysis of the code will result in greater transparency.
