Exactly, consider also some projects and exchanges that collect money for random projects before they list their coins. Means, it is a listing fee. I believe that this is very famous in most exchanges. I believe this still exists for some exchanges.
Just take a look in DEX (decentralized exchanges) how projects are being rugged, it's example of manipulations that you can witness live and sometimes happened in just few seconds or minutes.
Listing fee can include a coin or token of that project and you know exchange will try to maximize money from a project coin or token. They are parts of market makers and are ready for market manipulation or at least price manipulation on their own exchange.

With their new CEO, Richard Teng, binance changed to easily listing coins like Bittrex exchanged used to did years ago.
