I'll put myself at least partially in the "true crypto believers" group, but I think this is good news. Stolen X is 'bad', bringing the people who stole X to justice is good.

This is where I may only be a 'partial' member: My feeling is that Bitcoin (not all cryptocurrencies) was about removing Fed/Gov control of the currency. It takes no position against law enforcement of direct currency theft - outside of what could be construed as the theft of currency value by quantitative easing / gifting bailout money to banks, etc.

Bitcoin, specifically, has always had a public ledger too, so start-to-finish transaction tracking is part and parcel.
