The puzzling thing is, why only crypto developers are facing this? Normal developers get by without any problems at all. I think they are being very selective here.
They are clearly trying to send a message to everyone with this arrests, and they scared many people by doing that.It's not an accident or coincidence that in short time period they arrested Tornado cash developers, Samourai devs, and some of the big names in this space like CZ and Roger ver.
I don't even think they have serious legal case against most of this people, especially with Ver who renounced his US citizenship ten years ago.
This is slowly happening in European Union, which i somewhat touched in this thread: https://bitcointalk.org/index.php?topic=5495068.0.
But we should trust their stupid CBDC crap will have any privacy? 
I will have to repeat this quote more often:
