Do KYC exchanges will delist LTC?

I’m asking about something else. Kyc exchanges follow AML law. In that case they can’t support privacy coins. But in LTC case they can not support deposit from MimbleWimble addresses only and still can support classic addresses deposits and still they are ok with AML law. So why this Korean exchanges delisting LTC if still classic LTC addresses are compatible with AML law? Maybe someone from LTC foundation should explain them this topic. They don’t need to delist LTC because if they accept deposits only from classic LTC addresses then they still are compatible with AML law. Maybe they don’t understand MimbleWimble feature is optional only?
