Why is Monero delisted?

Could you please explain to me the reasons behind the delisting of Monero? I'm quite curious as to why this particular cryptocurrency was removed from certain exchanges or platforms. Could it be due to regulatory concerns, security issues, or perhaps a lack of interest and trading volume? It would be helpful to understand the factors that led to this decision, as it seems to have generated quite a buzz in the crypto community. Thank you for your insights!
