We do not have to be repeating what has been posted before, lock this thread.
There has been two other threads this has been discussed, especially the first thread:
Ouch, today someone made a transaction with over $500k fee.
Bitcoin User Just Paid Half a Million Dollars for a Single Transaction
It was later known that it was Paxos that made the mistake. F2Pool mined the block. F2Pool later returned the money.

You're late... F2Pool not only agreed to return the funds, but they already did it.

That was after some controversy with people saying they should maybe keep it and redistribute it to the miners... https://twitter.com/satofishi/status/1702095123981738437

These days you might have seen the debate where a single bitcoin transaction of 0.074 BTC, paid a fee of almost $500K, that is almost 19.8K BTC as a fee. This was mined by F2Pool meaning that the miners at F2Pool gain that much money. However, there is a debate that they will have to return this money as it was due to an error or bug at Paxos end.

I am not sure if the miners will agree to the refund

While Paxos asserted that it had initiated contact with F2Pool to recoup the funds, the miner no longer seems eager to agree to a refund.
