He's more like a shitty doctor who botches an unnecessary surgery and then is overly brutally honest about the bad news. He could have just not said peep, slunk back into obscurity after being famously outed as Not Satoshi. But no. He had to press his ego on the crypto world and now his #1 pet project is down over 50% in 7 days because of it.
If miners process transactions on the blockchain that are involved in illegal activities, and this is clearly visible, then they are at risk
It is far better if miners never know what any particular tx is for, otherwise, CSW's warning is valid, miners could be legally liable for KNOWINGLY facilitating illegal activities by processing tx into a block where the purpose is illegal, and this can be seen in the op code. Nothing really to do with CSW personally, or ethics, just legal realities of the world we live in today.
disclaimer: CSW is a dick, I agree!
