It was a very large transaction combining bitcoins from about 640 inputs. The sender could have saved a lot of money by waiting for fees to drop and paying 10 sats/vb rather than 100 sats/vb.
The only reason this transaction is even an issue is because no one knows what made him pay that fee. The sender may found himself in a situation where it was impossible to wait for lower fee. As long as it’s not a $5 wrench which forced him to make such fast transaction, no one should worried about it.
