Why is Monero not on Binance?

I'm just wondering, why isn't Monero listed on Binance? It's a popular and respected privacy-focused cryptocurrency. Is there a specific reason why Binance hasn't included it in their exchange? Could it be due to regulatory concerns or technical challenges? Or is it simply a matter of Binance's selection criteria? I'm just curious to know what's behind this apparent exclusion. It seems like Monero could be a great addition to Binance's offering, so I'm really puzzled as to why it's not there.
