Why did xenon get banned?

Could you elaborate on the circumstances surrounding the ban of xenon in the cryptocurrency and finance realm? Was it due to its potential for misuse or some other reason? Did it pose a threat to the integrity of the system or was it a regulatory measure? I'm curious to understand the specifics behind this ban and how it might impact the industry in the long run. Was there a significant community outcry or was it a swift and decisive move by the regulators? Your insights would be greatly appreciated.
