Also, people in crypto hate centralization and Binance has built the most centralized and groundbreaking company in crypto. Their use of the BNB token is something that will likely be studied in economics and business classes for decades to come.
And no one that is love by all, even bitcoin, it's hated by the government and some county even ban the use of bitcoin, so even if BNB has a lot of haters, what's important is it progresses and grow as one of the leading coins in the market.
Binance exchange is not fair. They usually become un-responsive at times when bitcoin is dumping or pumping. Recently they had a scam wick which moved upto 48K and liquidated lot of short position. These are the few things due to which people hate binance.
