My take on what happened:
Address bc1qn3d7vyks0k3fx38xkxazpep8830ttmydwekrnl received funds, which were immediately transferred again. That happens to every compromised private key, and many bots must be competing to be the first to steal funds. Usually, they use a high fee. In this case, my guess is that since more and more nodes accept full RBF, this lead to a very high transaction fee. Eventually, miners will get all stolen funds and the "private key hunters" will only be left with crummies. I hope the real owner can convince Antpool he's the real owner, so they don't send it to any of the private key hunters who also have the same private key.
