As basically a sidenote to that lawsuit, SpaceX more or less said "Oh and by the way, how is it that they are buying engines with these sanctions in place?". It was a rather tangential issue to the lawsuit itself. All SpaceX did was publicize that issue, everything before and after that was entirely the governments doing (the sanctions in the first place were on the government, and the injunction on the ULA was placed by a judge, not SpaceX. The injunction was lifted, again by the government, and the governments currently poor diplomatic relations with Russia inspired Russia to essentially make the injunction stick) In other words, the ULA is just whining that SpaceX tattled on them. Any real blame lies with either the people who made the rules, or with the people who broke the rules (or both).
