It's indicative of a larger trend within crypto, which is the trend of regulation and much tighter restrictions imposed by governments and intergovernment organisations.
That's a part of the reason why people's tastes have shifted towards altcoins which have real life implications as opposed to privacy alone, and also a huge reason why the price of Monero, ZEC, and Dash have continued to slip despite BTC's bull runs earlier in the year.
Don't be surprised if other exchanges, even Binance, start delisting these anonymous coins one by one as they become more "compliant" to international regulations and standards. Unfortunately, this is one of the prices to pay for more matured regulatory measures.
