People tend to always focus on the negative aspect of mixing and whatnot, while they completely forget that the same privacy hackers enjoy, is also beneficial to all of us normal folks. Criminals use what they deem useful (Bitcoin, cash, gift cards, prepaid debit cards, Gold, etc) and whatever they deem useful is also useful to us. In that regard, I'm not bothered at all by articles like this.
I'm very much looking forward to how upgrades such as Schnorr will change mixing in general. It shouldn't come as a surprise that authorities won't like to see such advancements in Bitcoin because it took them years to get to the point they are today, so imagine how long it will take to catch up this time with much more privacy enhancing functionalities baked into Bitcoin.
