Though I swear I recall reading some ominous wording, pointed out by another commenter, that subtly suggested the decision to quietly settle vs. aggressively prosecute was based on billions of dollars of potential economic fallout. Other articles [2,3,4] talk about contagion risk, but none are exactly what I recall. Funny how memory works!

Anything important won't be built on something they can't control or manage. Crypto by definition is that. So you have to really consider what this built on it and who's profiting from it.
"No contagion risk" doesn't mean nobody would be harmed by a crypto collapse; obviously there are a handful of morons here and there who would get wiped out. It means there is no systematic, widespread dependency of the real economy on the crypto one. I think the bank failures bear that out.
