Random piece of news stating the guy was arrested not as a TC developer but because he was actively involved in cash recycling.
Not that this changes much in the situation, but it is only a bit less worrying as he wasn't arrested for only writing code.
Do you have a link to it? I was thinking that something along those lines was what happened.
Although not 100% the same it goes to the automotive world of emission control defeating devices. They are 100% legal to buy / sell / own / design / build and so on. You just cannot use them on any car that is run on public roads.
I see a lot more of this happening over time since a lot, could even be most or all of code that does mixing is open source. It's pointless to even bother with the developers. You go after the people running it and making money from it.
