Why was Ripple banned?

I'm curious to understand why Ripple was banned. As a leading cryptocurrency, Ripple has always been known for its fast and efficient payment settlement capabilities. It's surprising to hear that it has been banned, especially considering its popularity and widespread use. Could you please elaborate on the reasons behind this decision? Was it due to regulatory concerns, security issues, or some other factors? I'd appreciate it if you could provide more insights into this matter.
