It's difficult to overstate how significant the monetary and organizational overhead was in dealing with SO's will they / won't they in the past year for us (with 1000+ developers working on 3000+ repositories). The result is a complete and total ban of SO-sourced code (or prose), with static analyzers and regular audits set up to purge them from existing and future code.
Plus, this whole thing has done nothing to improve legal's stance (which I can empathize with - in this specific case) on open-source, damaging efforts that had been in the works for a long time.
