English wiki Unsourced BLP Drama Pragmatic Review
I'm glad to see ArbCom taking affirmative steps to encourage consensus building. (Instead of the usual negative step of "not our problem, figure something out you guys".) I'm not sure I read the motion as being under the knife like you do. Is ArbCom really saying that 50,000 articles will be deleted if they don't compromise?
I don't see it. But if they are, you're right, they'd be designing a "good side" in the dispute. It would give that side a huge advantage in the negotiations, and make consensus-building more difficult. The "big stick" approach will encourage compromise much more if editors think the big stick will come down somewhere in the middle. If people think the big stick will just back them up, they might stonewall and take advantage of that.
But again, to be clear, I'm not sure I see ArbCom doing that here.
