Most especially when it comes to getting listing on Binance as that act can simply be classified as extortion.
Binance don't have a listing fee. Projects which are interesting in being listed on Binance are encouraged to make a donation to their charity initiatives, but there is no minimum donation, and the size of the donation does not impact their decision whether or not to list you coins. See the links below:

The exchange needs to review it, ensure it complies with any standards or regulations they may have set, set up an interface for it, generate deposit addresses for users, set up hot and cold storage, build back end systems to handle deposits and withdrawals, train staff on using the new coin, potentially insure it, the list goes on. They have ongoing running and maintenance costs, staff wages, and yes, profits.
There's also the factor of high fees being an intentional barrier to entry. If you are demanding $50,000 to list a coin, then you immediately filter out 99% of the new scam coins which are launched every day.
Some of the fees are high, I won't deny that. But exchanges, being private entities, can charge whatever they like. Don't like their fees? Then don't use them.
