I don't really see how it's possible to be transparent about decisions for something this large without it being somewhat complex to follow the paper trail. If enough stuff from a discussion is written down, it's going to be complex. If the discussions aren't recorded in a publicly accessible way, that's clearly even less transparent. And if the scope of the discussions for something as large as Wikipedia haven't scaled with proportion to the amount of content being discussed, most of the decisions would probably not have been discussed at all, either due to individuals making them on their own (which is not particularly transparent, since there's no visibility into how they reached those decisions), or it was automated in some way (which is at most only as transparent as it would be to have the human who implemented the automation directly in charge of making the decisions, but in practice often is the least transparent option of all because most of the time automated moderation is almost always relying on ML or something similar).
