The fee was adjusted from 0.0002 BTC to 0.001 BTC. That means the increase is 5 time higher than before. You can see Stompix explanation about how Binance still make money because they send to many addresses at a time, but Binance has to consolidate inputs too though.
That is a pretty high fee it's around $30 they are making profits on transaction fees even though they own a mining pool they do still ask for high fees which are unfair. It is more likely they forcing people to use other networks including their own network to keep them active and currently, there is no lightning yet under the network option when withdrawing BTC. Meaning it is not yet enabled I can only see 3 options Bitcoin, BEP20, and ERC20.
