Strange Eth transactions are being send to Binance and Tether right now. Whats going on?

Ethereum gas fees have skyrocketed for the second time today. (https://ultrasound.money/) Currently still way over 100 gwei.

A large majority of the transactions are currently being send to a account called Binance 14. The strange thing is that all those transactions are somewhat small, yet often exactly the same amout ( 0.484599504 Ether Ether for example in this block (https://etherscan.io/txs?block=16149393&p=9). There also seems to be a lot of money being send in also very small portions to tether.

This is all very weird, why would someone send all of this money at once through so many different accounts? This obviously makes the ethereum fees skyrocket and whoever is doing all of those transactions is paying the bill for that. I am unsure what exactly is going on and if this is some type of attack. Does anyone know more?
