Binance is a huge amount of money capable of even manipulating the market both in a speculative aspect and in a psychological one. There is only one real reason - money.
This is the flagship that sets the direction of stock trends. Of course, other exchanges are not happy that Binince have so much influence and allocate a lot of money for FUD.
I think I've seen that competition and hate by other exchange for Binance. But to mention the hate, it those countries or some officials of it that don't see the significance of Binance.
But even if they dislike it, they prohibit it. Binance is already huge and can manage to operate to other countries since there are other huge markets that they have to be there.
The hate goes hand in hand with all the problems Binance has and what I believe is that the crypto community is a bit disappointed that Binance now becomes massively regulated, applies software to track user transactions down and will most likely forward all our data to legal authorities and regulators. Binance was one of us all the time, stood for decentralization movements even though Binance itself is centralized. But it did so much for the market and the community and all those efforts will now come to an end to some degree. Maybe that is where the hate comes from.
