As others have pointed out in another post, you don't reveal that you've broken an important cryptographic algorithm over $2M.
This was about principle and demonstration of capability.
If it is true the US has the ability to calculate BTC wallet keys as fast as it did, the price should fall.
Still not worth it if a crpyto function has been broken. If it was because of the encrypted chat app honeypot they ran, it might be different, but even then, only if criminals are moving to something else.
They also don't have the perpetrator.
If the US has the ability to quickly break a BTC wallet, it is a public demonstration of warfare that should act as a deterrent in other theaters of war.

I don’t think we have a full manifest of who was involved in the colonial attack or the personnel that have made up Darkside.
Even if we did, successful pressure on the perpetrators or their successors does not require holding the individuals directly.
