This would mean admitting the allegations are 100% true and harming their business even more with the risk of losing it all in worst case. Now we can assume it's not as simple as SparkFun makes it. It's a dirty situation, but necessary, and justified if they are really a victim.

SparkFun started the war, AdaFruit seem to only defend here.
