These are some of the reasons why they delist a coin
Commitment of team to project
Level and quality of development activity
Network / smart contract stability
Level of public communication
Responsiveness to our periodic due diligence requests
Evidence of unethical / fraudulent conduct
Contribution to a healthy and sustainable crypto ecosystem
It seems the main reason is "Evidence of unethical / fraudulent conduct", because of the actions of their developer, I don't think it will just disappear unless all exchange will band and agree to delist Bitcoin SV they still have demand in the market, and the market is still good.
