It is bad news. In fact, Binance and a bunch of other exchanges may be illegal within your jurisdiction too. Something being illegal by law doesn't make it by definition is a scam. The only thing China cares about is to lower the freedom people have, and by shutting down exchanges people have fewer options to buy/sell Bitcoin.
China hasn't done anything as far as I can remember to help its people. It has done a lot that I know to work against them, punish them harhsly and control their life where possible. People there are getting scammed more by their government than actual scammers.
