I read about this yesterday and I still don't understand what is "new" about what they are doing here. we have always known that there were companies doing blockchain analysis like the one owning the walletexplorer.com website, and we have always known of different methods to "unreliably" track transactions in the past too. and so far nothing has changed about blockchain to change anything about their methods.
While they say they are doing this in order to track crime on the blockchain, many view it as an invasion of privacy on the network which leads to mistrust in other participants.
What are your views? Do you think that it is more indication that users should consider privacy conscious coins?
I don't consider this an invasion of privacy because we have always known that all our transactions will always be stored on the blockchain for everyone to see. so we knew what we were getting into and bitcoin never promised high level of anonymity and privacy either.
and people who want to do illegal activities and hide their tracks will use either cash or truly anonymous coins like monero and I don't see why this has to change just because of this news.
